I manage my cables like I manage my room... it may take some digging but I can always find what I'm looking for eventually.

[Revv23]

wow i didnt see all of that.

i didint realize those pieces of copper were live...

I wonder how the PSU handles that.

[2fink]

looks impressive!
perfect german work ;)

[Sumanji]

Man, that's amazing :eek:

[sladesurfer]

Made my rig looked like i didnt paid attention to it :(

LOL, couldnt agree more.

sick! impressive work!

[J-Mag]

so I guess it is easy to shock yourself with that case then...

[LvMike]

thats a damn stupid idea, but it looks good. I would never run live rails like that through my system. just to many things to go wrong.

[aMp]

Live rails, water cooling, what could possibly happen?

[majestik]

I guess thats why its so Xtreme

[day187]

very nice

[Sumanji]

XXXtreme tbh :p:

[potkit]

what about the change on the magnetic field. it could blow the motherboard out

[XS Janus]

very cool, and very inspiring...
But those live copper really is trouble waiting to happen, maybe some type of transparent paint in a thicker coating could help...

[aMp]

I actually think it'd look cooler with a cylindrical acrylic sheath running the length of the copper rods. It'd fasten right to the existing mounts.

[smopoim86]

Crazy or not, it sure does look sweet

[dinos22]

this modster is a freak

imagine his house

pens lined up nice and neat heheheheh

[whoodiestyle]

wow he went to the extreme on that

[cky2k6]

some poor unsuspecting soul will reach into his computer, and, well dinner will be served... seriously, i think that its quite foolish, but the work put unto it is astounding. i would be more worried about his hard drives then his mobo.

[SparkyJJO]

The voltage from the PSU isn't gonna be enough to shock anyone, it is only 12 volts after all. The only danger I see with the way he has it is the possibility of shorting them together (loose screw for example).

[古強者死神]

Yeah thats not a human threat, it wont shock you but it could end the systems life instantly if somthing shorts it out.

More than the power rails wich I think is neat, is the fact he said he soldered all the ATX stuff directly to the mobo from the backside. That is what I think is the bad idea. That mobo and maybe the PSU are pretty much set in stone to never be used for anything else, for sombody like me who has had to remove his psu, mobo, ect ect on several occasions to do a mod, clean, and other things this would be a very very bad idea.

So in effect its very showy but fails to perform IMO.

You see just about as many wires in my case due to neat cable managment, but they still come right off the mobo when I need them too.

[w00t!w00t!]

That's beyond sick

12 volts at 30+ amps is alot of power my friend.

It only takes a few v to stop your heart.

[exhausted mule]

""It only takes a few v to stop your heart.""



volts is the potential electrical difference between two objects and amps is the amount of current. current is what kills.

as purdy as those rails are you wouldn't want to be rubbing them when the psu is on.

[BlueWonder]

mm, current is the one that pwnes.

This is pretty extreme, but even so
I wanna see liquid cabling dammit.

mercury maybe?

[exhausted mule]

liquid cabling???? wow.

tell me though, what benefits would this have over conventional cables?


here's a nugget for ya, i'm am soon awaiting a set of pure carbon cables. 48 000 filiments in just under 3mm.

should be interesting...

[Sorrow13]

dangerous or not, well done on the XS spirit. Next up: Hardlines for IDE /sata cables?

[PowerSlide]

this is xtreme system not xtreme caution forum :p:

[lawrywild]

liquid cabling???? wow.

no, that's his watercooling :slap:

we're looking at the copper rods..

[exhausted mule]

Ohhhhhhh


ok



:up:

[n-sanity]

Oh **** place a ferrite/iron rod between the grounds...EEEK. If a powersurge ever comes, not only the mobo will get knocked. Prolly like everything in the room :D

Btw, i bet that doesnt comply with fcc rules :D

[n-sanity]

Just to let everyone know, human skin can resist up to around 35v, and rough skin (lumberjacks and boatmen and such) can do up to 60v. My uncle used to be a serious competitor in single kayak races. He was an electrician by proffesion. He's russian btw. No safety involved. Touching bare live midvolt leads was his proffesion.

[massman]

12 volts at 30+ amps is alot of power my friend.

It only takes a few v to stop your heart.

You can die of 50mA.

[jaguarking11]

enough of the stupidity. Youd have to have the 12v rails connected directly to your heart to die from it.

he did an excellent job. It looks good and works well. Thats all he wanted to do and he accomplished it. Unlike you guys, I don't take my machine apart every day and im willing to be neither does he. He did a good neat job. I kinda wish I had the room to do something similar to my case since I already have hard liquid lines in my loop. But I run a mid tower and have no were near the room he does.

enough criticizing. Different things are for different people. Not all apply to everyone.

I tip my hat to him. Good craftsmanship.

[SparkyJJO]

Well, I've held bare wires connected to a PSU before to keep them in place when messing with stuff and haven't gotten zapped yet.

Note the operative word there, "yet" ;)

[VAdept]

Its very impressive and definately somehting I would call xtreme. The attention to detail is stunning.

[[XC] MarioMaster]

sheesh 12 volts isn't gonna kill you, hell you probably can't even feel 30 volts

does touching a car battery kill you? no. does it have a large capacity of amps? yes.

in other words, touching those metal bars = fine, touching those metal bars with something metal (screwdriver, etc.) = bad

besides, i think it's manditory for all computer psu's to have short circuit protection these days, i've shorted my psu a couple times by accident, no sparks, smoke or explosion, the psu just turns off

[Dubz]

that is extremely sick. i only wish i had the time and skills to do something like this. totally awesome work.

[phelan1777]

wonder if he is an xtreme member?

That is mad crazy!

Okay... that kinda voltage won't penetrate normal skin, but a touch of moisture etc... hello Mr Defibrilator. as has been said, current kills, not voltage. and it takes surprisingly litle to upset your heart (I have a condition (Wolff-Parkinson-White syndrome), which involves the electrical pathways to my heart, so I have read up a fair bit on this)

While we are on it... current is not supplied as such, but requested/drawn from the power source... your car battery may be able to supply 300A, but unless a component (starter motor etc) draws that power down the wire, then there is no current.

Short circuit protection? Great, your PSU lives, you don't, a lot will not ract quick enough to save you.

Just be careful out there;)

ANYWAY.......

Cracking Mod... original thinking, especially on the support arrangement.

[Thrilla]

lol I was thinking about similar things, saw those lights hanging on steel cables at a bar, my idea was to use tiger clamps lol, but the copper pipe beat me to it.

what i really like is how hes got all the wires black, its a wonder he didnt mix them up.. lol.

[cirthix]

impressive, but couldnt he have just routed cables behind the motherboard?

[fhpchris]

12volts at 40+ amps is a :banana::banana::banana::banana:load of wattage, and that is what kills. not voltage or amperage.

Putting live copper rods in a water cooled case is just not responsible.

[LazyBum]

That's pretty sick I like it :) I worked as an industrial electrician for an number of years so I really like the craftsmanship and style, reminds me of high voltage busbars. If it was me I would put a layer of clear acrylic or something on it to guard against accidental shorts, although the psu would trip before you would do much most likely. Safety wise I don't really see any danger, it's only 12v, not enough to cause a shock.

[Pete]

He solders some of the wires directly to the back of the mobo!!! Mental

[hypocriTe]

Well the electricity would follow a path from source to ground right?
So if you touch the other wire while holding something else (metal) it could flow through your heart and kill you with relative ease.

Correct me if i'm wrong.

Back to the mod:
It is definately extreme but I think I see as many cables as some conventional wire management cases.

[MrBean]

a Very novel idea. I like.

Well done.

By the way, guys, doesn't help you have a dam (current) and no pump (voltage) to transport it with ;)

DC can do a lot more damage than AC, but you need roughly 40-50V's to be dangerous.

[pablo]

1 amp can kill you if it travels through your body the right way. ive worked on 30,000 amp boxes before in big warehouses. you can stand 20 feet away and hear the electric flowing. you wouldnt even know what happened if you screwed up on that.

[STEvil]

nothing wrong with how he did the voltage "rails"

if you manage to shock yourself with 3.3/5/12v DC then you probably deserved it.

[Holst]

Impossible to get hutr on that IMO, unless your stupid enough to lick the 12v rail and the earth, which might tingle a bit.
You wont even feel it if you use your finger (well I wont anyway)

Have you guys never licked a 9v battery to see if its charged or not?

[jimwah]

I licked the adapter for my game gear when I was a nipper, and I'm alright :wth:

[FLMJIGGY]

It is beautiful. Really isn't much more to say. I'm sure there is a way to cover them, like sleeve the copper, but that would be more work. Awesome!

I saw that a while back and never really put it together that it was his power running through it!!! lol

YES! I also tried licking a phone charger (not a new phone, one of those huge early nineties mobile phones). It makes your whole toungue taste like metal/sour. Must be the electricity stimulating the toungue or something.

Anyway, that mod is crazy, and pretty dangerous (to his computer, not his life). Amazing workmanship though. If he somehow protected the rails from any exposure (maybe put a vacuum sealed glass/plastic tube around them, like a flask), it'd be alot safer.

a guy in my city has a uglish case as he doesn't have tons and tons of cash to spend but his water loop is copper piping thats nice and polished with copper joints and such -- his wiring is the same thing basically looks space tech

[flavoraid]

if you touch the copper tubes will your face turn into a light bulb?

[zabomb4163]

if you touch the copper tubes will your face turn into a light bulb?

we have already established that human skin has too great of resistance for electricity to travel through it (reason insulation around wires works)

[flavoraid]

it's metal --- how bout you try it ... personally im not going to touch something I know has enough amps and watts to kill me along with the fact it is a conductor.. you try it and maybe I will after.

Ever put a finger on each terminal of a 12v car battery? You don't feel much...

[flavoraid]

car battery licking is bad :(

specially since your tounge is so close to your brain

but people can get shocked by them else where and not die correct?

[zabomb4163]

yeah but just one AMP across the heart = Death

have you ever unplugged somthing from the wall? if the answer is yes explain why your still talking to us here on the forums. For that matter why does your house have electricity? why doesnt the electricity just go straight from the power line through the pole down to the ground.


ill give you a hint: "sufficiently high resistance relative to voltage"

[Snatch]

That is extremely nice and crazy.

[ziddey]

I don't understand how this is xtremesystems and more than half of us aren't understanding electricity. I thought it was well established in high school (middle school even) about things like this. You can touch it you'll be fine. You can wet your hands and touch it you'll be fine. You can lick it you'll be fine. If you lick both the 12v and the ground, it'll be fun kind of


Have none of you licked 9volt batteries?

What about have any of you messed with cable modems? The transmission through those can be ~48V or so AC. Hold the bottom with one hand and the coax cable with the other. Go against friends and see who can hold it the longest. See who ends up with bloody hands

[Insight Driver]

Being an electronics tech I think it's so cool. The bars are rigid enough and you could grab them and not feel a thing, the voltage is so low. If you did feel anything, it would be maybe a tingle. I imagine the resistance of the pipes is so low that you have very low voltage droop due to wire resistance. Of course, that's akin to the improvement in mileage you get if you wax your car finish. I don't mean to diss this work, because I am of the opinion that it is a great example of being extreme; something to be really proud of.

[Revv23]

i agree this wont harm you, but lets not go so far as to say electricity wont harm you, some people get struck by lightning and live, others get electricuted by a wet extension chord and die. (happened in my area)

Fact is its not a good idea to electrocute yourself. I however would not worry to much about having this case as my own.

[rob[GL]]

That is pure sex!

[Vizion]

Yeah, if electrons don't find a least impedance path, and it finds you, they will definitely go through you to the ground, if the potential themselves and you is large enough to cause a flow.

The most effective way of making a path through your heart is your 2 hands, 1 straight line across. The shorter the path(closer to your heart), the more deadlier . :D

So yeah, touching those rods won't hurt you because electrons don't want you to be its path to the ground anyway, they found better path which is the rods.

haha oh yeah using both hands is a lot more fun. i remember when we used to play with those flash camera capacitors (roughly 300-450V), I soldered two leads so people could try using both hands. I thought about making some sort of game (or studying tool) where you choose answers abcd or something by touching. Meanwhile you'd have the other end of the cap wired to your other hand. Choose the wrong answer. BOOM. Only one person thought it was a good idea, saying it'd be very encouraging during studying to quickly learn the right answer. hah

[The Mutt]

A DC current is not dangerous to your heart, not in any computer PSU thats on the market for years :) But AC current kan stop your heart, because your heart tries to beat at the same frequency as the AC current ex: in Sweden we have 230Volts and 50Hz frequency, if you get electricuted your heart tries to beat 50 times per second instead of something like once every second and thats not good :) But a DC current can be dangerous if it penetrates the skin, and can coagulate the blood at the contact points and that can lead to blood clots and that leads to a stroke AND that can kill you.

But his rig is moderatly safe if he isn´t afraid of shorting something and doesn´t plan on licking the rails :D
And everybody should appriciate that he has done something new! Great work!

I have english as a second language so there can be some faulty translations of the tech talk :)

[\Karting_freak]

i put my fingers in 220v
when i was a child
now i only have a scar on my finger..


BTW any1 explains to me how it works?

[irev210]

while the 12V cant overcome your skin, it can burn you.

If you wear a watch or something, the metal on the watch can heat up and burn you.

I think many people need to learn about electricity a little more heh. Im sorry, but I was laughing out loud when people were saying they were afraid of "lots of amps". I'd be afraid too, if it was 35V+

[phelan1777]

fingers, we don't need no stinken fingers!!

[SPL15]

Thought I would clear up some stuff for you guys.

if your talkin about just current killing, then a AAA battery could kill you.

If your talkin about voltage killing you, then getting a static shock could kill you.

We all know these two statements aint true.

Like has been said before, your skins resistance means that at 12volts the 50ma to 70ma of current cannot be reached because resistance is too high for that amount of current to flow.

Electricity kills by asphyxiation (aka suffocation). It paralyzes your heart and lungs and disrupts your brain which leads to oxygen deprivation. People struck by lightning usually die of internal burns through their vital organs, but sometimes from asphyxiation from their brain not telling their lungs to breath or heart to beat.

A static charge must be about 6000 volts (yes 6KV) before you can even feel it. Static discharge as low as 30 Volts can destroy CMOS transistors in IC's. Static can jump about 1 inch per 1 million volts.

AC voltage is considered to be more dangerous because 120Vrms AC is 170Volts peak to peak which means more peak current flows through your body. DC voltage is just as lethal as AC voltage when absolute values are considered. For example 170VDC is just as deadly as 120Vrms AC. Either is more than enough to paralyze your heart and lungs.

Thomas Edison was NOT the father of today's electric grid! He wanted a power station producing DC voltage on every street corner. Nicola Tesla with westinghouse produced AC power distribution we know today. AC travels long distances with minimal losses partly due to the ability to step up the voltage to hundreds of thousands of volts, but also because ac has less impedance over long distances compared to DC. Edison was a monopolistic jerk in reality. Nicola Tesla was a real genius who still doesnt get credit for the biggest change in human history.

Also you cant hear electricity!! That humm or buzz is caused by magnetic fields in transformers creating movement in panels, windings, etc. Electricity is silent it can only cause other things to make noise.

The most deadly voltage is 220 to 480 volts AC. With 120 VAC you can still force yourself to let go. With 500VAC or more you get blown away or fly back from the source. With 220 to 480 you touch and are immiediatly paralyzed and stiff as an iron I beam and no one can touch you cause they will be the same AND it usually wont blow breakers because your not passing enough current to trip breakers. The movies have electrocution all wrong. In real life it is much less dramatic. Basically you sit there frozen or tense up in the most intense pain you could possibly feel and pee and maybe poo your self till you suffocate to death.

It is commonly thought that voltages above 50 volts are dangerous, and below 50v it is not considered lethal. Depending on conditions, this is true. If your dripping soaking wet, a car battery could maybe kill you if you grabbed it tightly on both terminals, but it would most likely burn the hand on the negative terminal.

Electrons travel from negative to positive in reality. Conventional thinking back in the day was that electrons moved postive to negative and circuits are often designed with this false notion. Either works in theory, you only run into problems in certain circumstances with high power or extreme high voltage.

As long as that case is sealed and not easily opened and the case is fully grounded, it is fully safe and could probably pass for UL license and that kinda stuff with a few minor tweaks.

The DC voltage drop would be better than normal cables in normal power supplies, but I doubt this will have an effect on performance. In real world use, this buss type system would have worse performance because the current use by computers is VERY transient and busses like that are poor performers for transients. Constant current loads are good for busses, when your dealing with transient currents, you'll get whats called skin effect. The current travels on the skin of the conductor and not through the actual conductor. Stranded cable has lots of surface area which means lots of surface area for transient currents to travel on.

The magnetic field being created by the buss will be a little stronger than the magnetic field created by your regular cables, but it will most likely not cause problems. If anything it will generate a little EMI which will probably be less than your hardrives make, and far less than your FSB/MCH connection on your motherboard.

The reason your tongue tastes funny when you lick electricity is because of a chemical reaction. I forget the proper term, but the electricity is causing a chemical reaction in the spit. I bet if you lick a 9 volt battery, the negative terminal gives you the most tingle and taste.

If the guy were to smoke crack one night and stick a scredriver into the case and short the rails, the power supply would sense the short and shutdown. If it is a crappy power supply it might produce a large voltage transient to compensate for the sagged voltage and destroy parts and then it will short out the main switching mosfet in the power supply from overcurrent that is caused by oscillation from severe overcompensation of a switchmode power supply and then the main fuse would blow wide open. The worst that could happen from a direct short would be damaged parts.

If the guy is good ( which he appears to be) then soldering the ATX connections directly to the mobo would make the absolute best connection you could ever fathom of getting. Yes, it WILL be a pain in the butt to do work on the mobo, but cool looks and performance often come at the expense of practicality.

This is the cleanest looking case I've seen period. And I would say it is FAR safer by a magnitude of 100 than 95% of the Vmods I see people have rigged on these forums.

Basically to sum things up:

The guy is in absolutely no risk of hurting himself or others with this mod.

12 volts could maybe kill you, but you would have to be trying pretty dang hard to do it. Basically stick one terminal from a car battery on each of you nipples dripping wet with salt water.

According to established rules, 50 volts and higher is considered dangerous.

AC is just as deadly as DC.

[ziddey]

Wow that was extremely well written and I learned a bit from it :). You should post more ;)

One thing I noticed in particular that you mentioned that I was told differently by my physics teacher way back in the day was that the 240v in europe is safer than the 120v in america. He mentioned that the 120v in america operates at 60hz, which he said was also the frequency at which the nervous system works in humans (and also heart), which is why the paralysis exists when you come in good contact. He mentioned that the 50hz in europe poses less of an issue since it doesn't interfere with nerves in the same manner.

What you are saying definitely does make sense though. I've touched 120v ac a bunch of times (most of the time it was unintentional but nonetheless), but I just figured it was because I was always touching thin wire, which could just as easily fall and release, as opposed to full out grabbing something.

but thanks for the post for sure. It was a good worth of my time reading it and I was a little sad to scroll down and see that the end was near ;). I'm sure it'll set a lot of people straight in this topic

12 volts could maybe kill you, but you would have to be trying pretty dang hard to do it. Basically stick one terminal from a car battery on each of you nipples dripping wet with salt water.
According to established rules, 50 volts and higher is considered dangerous.
AC is just as deadly as DC.


I have to sig this cause I thought the example was funny.

SPL15 thank you for your post, its one of the best I have read yet.

One thing I noticed in particular that you mentioned that I was told differently by my physics teacher way back in the day was that the 240v in europe is safer than the 120v in america. He mentioned that the 120v in america operates at 60hz, which he said was also the frequency at which the nervous system works in humans (and also heart), which is why the paralysis exists when you come in good contact. He mentioned that the 50hz in europe poses less of an issue since it doesn't interfere with nerves in the same manner.

Sorry, I had the same issue in physics class with my teacher... Basically when it came to the mysterious and magical electricity part of the class, he spoke out of his butt.

50Hz and 60 hz are both equally lethal. If you were to grab 50 hz and then grab 60 hz, you wouldnt be able to tell the difference, it would just hurt.

What matters is the peak voltage. Your heart and lungs dont care about RMS voltage, the peak voltage/current is the current that your body will feel. Your muscles will tense with the frequency of the voltage being applied. Unless your NEO, you cant move fast enough to release 50 hz over 60 hz.

Your nervous system doesnt really have a frequency. Sure our bodies and brains sort of act like computers and peripherals etc, but we are a little more complex than 1's and 0's. Our perception and realtime multitasking would not work on a nervous system that had a clock of 60 hz. If you've ever been in an anechoic chamber, you can here a very faint ultra high pitch wine in your ears and sounds like its coming from the center of your head. This is thought to be a harmonic of your nervous system's "operating frequency" although it is probably just a wierd phenomena that means nothing.

Europe went with 50 Hz mainly because the towns and places that needed electricity were spread out much more so than in the US. Lower frequency AC will have less line losses over long distances and lower frequency AC was much more effective for driving massive industrial motors way back when. Nicola Tesla wanted 60 Hz and said that was a good number based on resonance and the fact that light bulbs back then didnt flicker with 60 hz, but did slightly with 50 hz. Also 60 Hz requires smaller transformers than 50 hz. The reason NTSC is based on 60 hz is because the power line frequency was originally used in the first TV's for vertical sync. Europe has PAL which is based on 50 hz... I'm glad we got 120 VAC @ 60hz thats for sure. It's less lethal than 220 and 60 Hz led the way for 60 Frames per second in TV (30 fields per second) which looks a whole lot better than 50 frames. Also, Transformers are need to be larger with 50 Hz... 60 Hz is worse for power factor, but oh well.
