I figured I'd finally do one of these, nothing to fancy from me though, I don't have nearly the patience most of the pros do here. My intent is testing function and easy changing out of parts.

First up...

THE CASE

I had to say goodbye to the TT Armor case, it's served me well for a couple of years now, but testing with it on it's side and having to cut a hold in the motherboard tray for waterblock testing was making me realize I like to tinker too much for a normal case. What I really wanted was something I could continuously change parts in and test on without taking a bunch of stuff apart every time. In addition I wanted somewhere to mount some large radiators...the torture rack fit my needs.

A special thanks to Andy here on XS for helping me out with this case...thanks!!:up:

FED-EX came at lightening speed as usual... and brought me this:

To be continued...

Thanks guys!

Don't expect much for show and detail here, but I am really enjoying this new build...it's working our really well, much more tinker/testing friendly.

Ok..on with it:

http://img522.imageshack.us/img522/6766/worklog03eh2.jpg
The first thing I noticed is I was wrong about how these things are cut. The burn marks on the paper and smooth side finishing is obviously due to some sort of CNC guided lazer cutting machine. This is good news because lazer cutting the acrylic provides a stress free edge that is much better for crack prevention than machining the shape, plus it's very accurate. Anyhow, lazer cut it is...I don't even want to know how much one of those fine machines costs.

http://img522.imageshack.us/img522/7098/worklog04rv3.jpg

Next I emptied out the accessory package, all the like bolts and nuts are all labeled and packaged individually. The printing on my lables was off a bit, but I figured it out soon enough, the part number 14 above was correct, but they are obviously not I-0 Shield screws...must have been a slip on the printer label feed. All of the screws and hardware is really high in quality.

http://img517.imageshack.us/img517/7809/worklog05ck9.jpg

And while I usually don't like reading instructions, this is one set that doesn't really require much reading. A very simple and concise diagram, in this case I need 9 each of the #13 screws to screw down the I/O shield.

http://img372.imageshack.us/img372/9615/worklog06hn6.jpg

And here is a view of the screw nut system. Each of the T or corner type connections utilize this sort of nut/screw system where you slide a little nut in the slot and tighten the screw down. This ensures a nice metal nut threading and a good mass of material receiving the nut load, it's a very strong connection and more than a simple threaded screw hole.

http://img522.imageshack.us/img522/7553/worklog07zy5.jpg

This is after step two, where you simply insert the nuts in the motherboard tray piece, match it up with the back and insert and tighten the screws. Most of the rest of the case pieces go together exactly like this, very simple and works well.

http://img522.imageshack.us/img522/7114/worklog08up2.jpg

And about 30 minutes or so later, the empty case construction was done (standoffs and reset button, etc not yet installed). I like the fact that the motherboard tray is designed with large access holes and standoffs. So the motherboard does get mounted securely like any other normal case, but it has alot of ventilation and access so you can change out block back plates and things. I selected the "UV Green" motherboard tray option to fit with the green them I was after, but you can pick any color.

http://img522.imageshack.us/img522/5650/worklog09yj0.jpg

Here is a better view top down looking into the empty case just begging for testing gear. It also comes with a variety of screws for mounting the hard drives, 3.5" drives, and 5.25" drives. Using only the supply drive holes, you can mount 2ea 5.25 drives, 2 ea 3.5" drives, and 4ea hard drives. I ended up only using two of the 5.25" drives, one for my DVD/CD burner and the other for my crystalfontz. Then I used one 3.5" drive for my internal multi card reader, and finally three hard drives. Two are raptor drives for my system and software sections and one larger storage drive for pictures and files. But this is assuming you only want to use the predrilled hole locations, later you'll see there is quite a bit of space between the hard drives, you could easily squeeze in two more if needed by either drilling your own mounting holes or making a hard drive cage to hold them. Overall I'm really happy with the options here. The most difficult part was figuring out what and how I wanted to mount and route everything.

I also happened to be browsing ebay a couple of weeks ago and stumbled upon these King Instruments flow meters. They are essentially the same model as my previous meter and the buy it now price was less than a 1/3rd normal price and so I had to swoop them up. I figured out pretty quickly that running my test flow meter in my CPU loop was a bit of a pain not having the meter handy to do other testing on the side. This way I can permanently fix the meters for each loop I have planned and still have on free for other stuff. Besides the "Twins" are also fitting of the "Twin 480 rad" theme I was working on...it'll make more sense when I get it together.

10-25-08 Updates

A little quicky update.

Not done with everything yet, but it is running with many to dos...

http://www.martinsliquidlab.com/img/Worklog11.jpg

This is the workhorse data logger. Not much to it, I don't even usually use the LCD part, just the one wire sensor and logging capabilities. It is the Crystalfontz CFA-633, capable of running and logging up to 32 temperature sensors and 4 fans with PWM control.

http://www.martinsliquidlab.com/img/Worklog12.jpg
This is my current block configuration. EK supreme on the CPU and Danger Den MCP chipset blocks on the NB and SB. D-Tek Fuzion GFX on the video card. Tubing is all TFC, I figured I'd try some of the 3/8" ID x 1/2" OD tubing while I was at it, but I kind of like the looks of the larger tubing myself, so I'll probably switch out the smaller stuff in time. Also note that the 120mm fan on the right is PERFECT for the Ram. I can happily toss that noise dominator fan module, and use a nice quiet and powerful 120mm fan to keep the ram nice and cool.

http://www.martinsliquidlab.com/img/Worklog13.jpg
Another perspective with the twin "KINGS" in action, still bleeding the loops out.

http://www.martinsliquidlab.com/img/Worklog14.jpg
After "ALOT" of trying different things, I finally came up with this configuration for my dual quad radiatior setup. This one is the TFC 480ER, and I used two TFC shrouds to pull the radiator away a little and provide clearance for the third fan exhaust. I didn't have any more shrouds other than four, or I'd use one more at the very top too. Pump is just sitting freely for the time being, going to work on some bracket/shelfs for both the pumps and the flow meters to attach appropriately. I chose this configuration so I can easily change out pump and it's all easy to access and work on.

For rads, I'm running one TFC480 for the CPU loop and one HWlabs 480GTX for the GPU/Chipsets loop. Both are 15mm fan spacing, so they work out perfectly. If I could find a way to mount my second 480GTX, I'd do that too, but I figured two 480s has some nice symmetry to it and keeps it simple for me.

http://www.martinsliquidlab.com/img/Worklog15.jpg
My current configuration, twin 480 radiators and twin King flow meters were sort of part of my twin theme. That's about as far as aesthetics goes, it's meant to be a tech station and easy to work on and change out parts. I'm pretty happy with it.

I really like the Torture rack, it would be perfect if they made the sides a little wider for two side by side rads on both sides (can we say quad quad rads?..:eek:), and even better if it was taller to accept quad rads without having to use the shrouds for the third fan, but this works pretty well. I'm happy with it, still need to build a few odds and ends brackets and shelves for the flow meters and pumps, along with maybe some custom reservoir, but it's coming along.

Actually Joel was asking me where I bought mine, so I went looking for a similar model. I think I paid like 50-$60 for the red one I've been using for a while now. When these listed for half that, I went for it!!

There's a lot of meters on ebay, I just haven't seen too many of these taller Kings, I think I like them more than the rest of my system...lol!

I'm having a blast with the new setup, it's just SOO easy to get to everything and the open horizontal layout on the MB is perfect. Horizontal seems to help with cooling alot of parts too, no more trapped heat and no more bending 8800 from all the weight.

Where you hide your PSU?

wait martin wheres your psu? :rofl:

Haha..that blue led fan you see in the center is my PSU.

That was another time consuming trick. I mounted it externally by the fan screws in the center so it's essentially sucking from the box in the middle of the back. Of coarse that wasn't as easy as simply bolting it up though. I had to take the PSU apart and glue a couple of 6-32 nuts on the fan housing to accept the bolts.

The rads all pull into the rack, so it has pretty clean airflow overall. I get secondary cooling all over the board from the rad fans as well, and the ram fan works really well cooling the dominator moduals. My little dominator fan module was starting to make alot of noise from the little fans that were going out, so it was perfect timing to replace that little nightmare.

Anyhow, I mounted the PSU at the back center both for better rad airflow and to give me a little more room to work internally. I want to be able to change out CPU block backplates easily, and I figured having the PSU internal would clutter the insides and make that a bit more difficult.

Martinm210
10-26-2008, 09:44 AM
The x-fire would be nice, but the OC'd 8800GTX still holds it's own even after having it for well over a year now.. I think it may be time for some video card voltmodding though.

I'm probably the only user with the Com port in use too, but that was actually one of the things I was looking for so I could use my com serial crystalfontz.

I work on a FPS game off and on, but not gaming as much as I used to. I still have Stalker Clear Sky and Crysis to finish up.

Martin I use some serial stuff too on my rocket electronics for data transfer and I use a Serial to USB converter. It's worked a charm so far with me. The one I use is made by IO gear.

Thought that might help you in the future if you ever do a upgrade.

I've heard about the converters, but never tried one. So far I've been lucky enough to pick motherboards with the capability still, but somehow I'm thinking serial is alot like 8 track...gonna have to change over sooner or later..:D

CF sells the Serial to USB adapters specifically for the CFA series. But, just about any USB to serial would work.

Sweet Martin! :shocked:

T_Flight
10-27-2008, 08:16 PM
It should work martin. My rocket electronics are known to be finicky about those converters and it's why I picked the brand I did. We had a couple that eventhough the right com port was selected in the program, it still wouldn't recognize the flight computers. I asked guys about that specifficly before I tried them.

You might wanna ask the folks that made it if they've had other users that have reported back to them and if they've found any that work real well. Most stuff gets along just fine though. It probably won't have any issues at all with any of them.

These rocket flight computers have some pretty special software, and they can be kinda finicky about stuff. Sometimes I think they have feelings. hehe It's like you almost have to talk to them and say things like "Look, don't give me no trouble up there, I'm counting on you." hehe

They're real easy to use. There's an end with a serial plug that's female and the other end has a USB. Sometimes you have to load drivers for some of them.

I use it on my laptop to download fligh5t data when I'm at launch sites, and at home on my PC to go over flight data and study it. I haven't had any issues with either computer.

Martin, your tech station setup is great, I bet it will be much more comfortable to work with for testing and tinkering ;)

Can you tell me exactly which King Flowmeter did you buy since I'm thinking of getting one myself for my own testing (since it's just mechanical, it can last a lifetime so it's a good addition to every serious WC enthusiast toolbox) ?

The King Instruments Rotameters (Flow Meters) are the 7520 and 7530 models, the 7530 has a valve body integrated into the body, thats the only difference. The other specifics are 10" Scale .5-5GPM. Look around Ebay for them, brand new they are more than an Iwaki, but you'll score some cheap on Ebay.

Thanks for answering, that's what I wanted to know :up:

This answer more precisely what to get : http://www.kinginstrumentco.com/pdf/7520_7530_Series.pdf

EDIT: poked the web a bit and you are damn right, it cost more than a Iwaki brand new. I didn't find one right now but I'll keep looking until I find one then order it (we never know ;)).

Yep,

All three of mine are the tallest 250mm scale type. You wouldn't really need that for general use, but the taller types are slightly more accurate than the shorter ones. I guess the 7520 is the type without a valve and 7530 is with a valve. I have two of the 7520s and one 7530, mine are also of the PVC type connections, the valve meter has a brass valve, and I'm not sure on the o-ring.

Thanks guys, going to take a little extended vacation from testing for a while, but I'll be back when the time is right. I just need a break from everything for a while.
Take it easy...Martin

I absolutely love this case, really tempted to buy one in the not so distant future for testing out parts etc.. Is there any other case on the market similar to this case ?
