The Antec Three Hundred Case Thread

[DX_Medic]

On the Side there is a second PSU mounted !!!

I just got one of these since newegg had a great deal on the case + antec's 500 watt earthwatts psu for $85 shipped.

How many fans do you guys think I'd need to cool a mobo w/ 4 video cards? I am currently using the case for a htpc, but my rocketfish stays too hot with that many video cards (its a folding farm) and I need much better air flow, so I'll switch eventually.

How many fans do you guys think I'd need to cool a mobo w/ 4 video cards?

The 300 comes with a 120 in the rear and a 140 up top. It has mounts for 2 additional 120's in the front. If you replace the stock fans with better ones and put some high-CFM 120's in the front 2 slots, you might be okay. A lot of your final temps are going to be determined by how hot well your video cards cool themselves to begin with. (I know, "Duh", right?)

I would definitely suggest doing some airflow mods to the front and rear fan locations by clearing away the stock sheetmetal and replacing it with some good free-flowing grilles. You might also consider doing a bottom mounted fan. Depending on how ambitious you are, you might even consider replacing the front-panel mesh with a more open pattern of modders mesh for better flow.

One thing that I would also watch out for is your CPU temps. I'm sure that you know how heat rises and your processor is going to be sitting there right above those 4 GPU's. I would seriously recommend a top-notch CPU cooler.

Another big concern that I would have is whether you will have room for all of those cards behind the 3.5" drive bays. You might end up doing some cutting to get the fit right.

Whatever you decide to do, give us some pics of the process and the end result. The 300 is a great case, especially for the price, and it should be used and modded more.

I'm thinking of getting some zalman ZM-F3's, leaving the 140mm fan as stock.

My folding farm is an msi-k9a2 and will be populated w/ four 9600gso's. They aren't long cards (shorter than the mobo itself). My cpu heatsink is an xigmatek s-1283, so I think I have cooling down. Folding only requires about 50% cpu utilization max for 4 cards in vista x64. As you can see, the cards do not move air out of the case:

I'll end up putting in a single slot card in the bottom since the heatsink will almost touch the psu and that hurts airflow too much.

I'll be doing this after Christmas, when I have a few extra bucks to spend on this stuff. Hopefully, I'll also pick up a digital camera so you guys can actually make out whats going on.

Sounds good, Killer! Hope you get that camera so we can see how it turns out!

Got all of the bays out of mine. 3x120mm rad is next.

I like how u've hidden ur HDD

Thanks! It stays nice and cool up there. I had to mount it upside down, but that doesn't seem to cause any issues. It's attached to the top of the case with a 3.5" to 5.25" drive adapter. I used the bottom tapped screw holes on the adapter to mount it to the top of the case.

Missing a side window??? That's what tools are for!!!

indeed

[Got_Vtec?]

that window mod just makes the case look a million times better, i cannot wait until i get around to pulling that dremel out

Your case is VERY clean! I love it!

[mattkosem]

Thanks. I think I'm pretty much done with "modding" it for now. I might cut a hole up top so I don't have to have the 12v connector routing over top of the video card, but I'm pretty content with leaving it how it is.

Broke down and ordered a TFC 360, an appogee GTZ, and an XSPC FC block. Should be good :-)

@ mattkosem

Good Job on your modify..I wanna see how you do the DVD Burners if you do some?

[OCX600RR]

Here's some from my recent build. Today I cut some holes into the case and finalized the cable management. Deciding whether or not to paint the inside black...

-Drilled holes into case for cable management
-Painted the yellow SATA cables black
-Painted rear I/O shield black
-Painted rear slots black (Including from g-card & sound card)

This is just insane.

Such a machine- watercooling, 4870x2 =10.5" and all in Antec 300? INSANE

I stuck mine in an aluminum Vantec external enclosure. There's no space for one in there anywhere anymore.

This is just insane.

Thanks! I just finished the upgrades last night. Here's a pic.

[MrMacke]

Since im getting rid of my watercooling and all that stuff, and getting a 4870x2 im allso gonna get a new case. So the big question is..... Will a 4870x2 fit in a antec 300? without doing any dremel work on the hdd rack?

Insane Brother but great job What kinda temps you getting off that
Cpu of yours? with that Big radiator you running up front?

Under Prime small FFTs I see 60C. I've seen as high as 80 on Linpak. These remps are better than the GT did, and I've got a video card in the loop too! I'm seeing peak temps of 40C on the GPUs under furmark.

could you could keep the top 5.25" bays and install a 240mm rad under where the 3.5" bays were?

Yes, I had an MCR220 down there before I removed the 5.25" bays.

cool i might give that a shot for my next build. kinda wanna go watercooling and i need a midtower so this case is hard to pass up at this price

i just added some blacklights behind my tinted window on my blacked out 300...

[mattkosem]

Installed the Detroit top on the pump and Ultra Kazes on the rad this week.
