Hi, im looking for a computer case that can accomodate 2 GPU cards (2x 7950/7970) and not run too hot, so i can take it to work to mine there with some free electricity. I have tried Thermaltake commander MS-I and it didnt work out too good. I want the cheapest possible case that can keep the temperatures under 80 C. Was thinking of this guy Antec DF-30:

I know that, but it would look strange having a milk case on a table at work wouldnt it? That's why i want a case for 2 GPU at work.

Buy an old computer case, hook up a bunch of block erupters onto usb hubs you've mounted in the case that are powered off the pc power unit, load in usb fans, mine inconspicuously.

he probably wants to mine scrypt...

Yes, scrypt. According to my calculations, USB miners will never ROI.

Cases don't really affect the temperature that much, what you really need is more/more powerful fans or water cooling. If you already have a MS-I, I'd recommend cutting a hole in the side panel and mounting a large intake fan. You can also hack up the front panel for better airflow. Also make sure that you have the fans all exhausting in the same direction E.G. Intake in front and exhaust in the back.
But if you're intent on spending a bunch of money the best idea by far is to improve the cooling on the video cards specifically. The ARCTIC Accelero Xtreme 7970 is a great replacement cooler for 7950/7970 cards... But it's quite expensive. I personally would try removing the stock shroud and strapping on additional fans with zip ties.
Anyway, the main point I'm trying to make is that the case is not terribly important to the cooling of the GPUs, what you need is more cooling.

I sold the MS-I case already so i'm on the market for a new one. The reason i'm asking for a good case for mining is, because some have already have good cooling solutions? For example already have fans fited in front/back/top. I would actually consider ARCTIC Accelero Xtreme 7970 if it's 100% that it would help. I checked and it costs 53eur wich aint that big of a deal. I now have 1 card at work in some random no-name case and it works at 70 C, 65% fan. If i put a second card in they both hit 85+ C with fan 90%+. I dont want an airplane taking off in my office How would that work, strapping on the fans? I have never tried/heared of that, got any additional advice? thanks

Cooler Master is a good choice as its fans are not wild boar!

I have 3 Antec 900's, very, very cool! But they kill any ROI you might get, which in it's own way is not ideal.
Better get a crate and hang up a few in there.

Water cooler is good but costly and I'm also quite worry about water leaking but I think it can be avoided easily if u build it right.
Anyway, what you really need is undervolt and it would reduce the temperature significantly.

Remove the side panel and undervolt the cards. My cards are running at 67ºC

it really comes down to the design of GPU cooler - most of them throw 90% heat into the case they're in. Along with that motherboard model (that is the distance between PCIEx slots) plays significant role as well - most have only 2 slots, there are couple (MSI socket FM1) models having 3 slots. 2 slots may only be good for blower design (like HIS ICEQ), not for "dual-triple-fan", found in most cards. there's nothing more weird than to waste $$$ for supa-dupa-c00l case; what you actually need is to supply cold air to videocard fans and NOT mix it together with the hot air - no case will help you with that. There's such term in datacenter design - "hot corridor"/"cold corridor" - and essentially you have to build something resembling it. In my experience with 2x5870 (sapphire fan design) it was very surprising that the best result was achieved when blowing hot air out of the front panel (2 120mm fans, one in "usual" place, other in 5.25" bay) and sucking in via the back of the case - the rig was built in an ancient extremely tight case, it's slightly higher than ATX mobo (like 32-35cm) and PSU was covering half of the mobo - cpu cooler was right under the PSU fan grill. The best idea was to locate videocards in a fashion that they suck air from the same location - achieved by placing them at 90 degrees ===5870fan===[pciex extender] || | cold || | air f| | intake a| | n| | || | || | [CPU socket] ====motherboard=====================
To cool fan-cooled videocard designs both inserted into mobo you'll need to install a fan into the side of the case - to blow directly between the videocards and this requires a 120-140mm hole in the side of the PC case plus sufficient width of it and a fan grill - for your fingers not to get cut off accidentally . HAF case in previous post has it. 120x38mm fans do wonders as well - but the noise is significantly higher.

If you worry about the heat, you should just undervolt and let it stay at stock clock.
Shouldn't be too hot, should be about 70c in casing.

That is right but why stay on stock clock and mine 500khs when you can boost your performance to 650 khs with better cooling and overclocking
