I have a cruncher that had been running in a nice Antec full tower aluminum case (an L1N64-SLI WS/B - a board that is notorious for running hot - with dual 2356s and 4 GT240s and lots of fans). CPUs ran typically in the 70+-80 degree range. (I use Everest to measure temps).

I acquired a HAF 932 case on eBay, and moved the system as is to the new case. To my astonishment, I found that the CPU temps had dropped by 15-20C to the mid 50's! (The vid. cards ran just a shade cooler, maybe 2-5C at best).

So the case made a tremendous difference. And it's purty. And it cost a lot less than going to liquid cooling or buying super-efficient air HSFs. (I use Zalman 7000s on my system).

Yes new cases have more vents, generally larger and more fans as well as usually being bigger to allow air flow. another ingenius design adaptation is placing the PSU on the bottom of the box which keeps that heat source away from the CPU

Good choice.

The second name of the Cooler Master HAF 932 is "High Air Flow". It's known
as a Case with a very efficient Cooling Solution as several Reviews shows.

I changed my case also.
Got a Antec Nine hundred.

Airflow is very important these days, specially for AMD Systems.

Hang on a cotton-picking bungle...

Multiple GT240s? I know they don't support SLI, so they can't be linked, but I guess therefore linking is more for gaming. A card is a card & if it's in it'll get units I guess.

(Standard Inspiron 531 case here - not the small form-factor.)

Yes - I use them strictly for CUDA, except 1 is also attached to the monitor. They were cheap (under $50 each) and they use little wattage compared to my old GTS 250s. And they don't require seperate plugs from the PSU.

Of course, they don't crunch as many WUs each as a GTS 250, but they do the job. They have 96 stream processors each, so they are about 1/2 a GTS 250 in that respect; however, they seem to crunch about 60%+ of what a GTS 250 does, so they are a better bang for the buck - and kilowatt.

I run everything side-off anyway, so no heat buildup in the cases here.

JRavin thanks for that - I know some of it but nonetheless very enlightening & further FGF (feel-good factor) about my September purchase!

I'm very inspired, but I think I only have a 300W PSU. Athlon64 X2 5000 - 1 HDD - 1 GT240 - can I safely add another card?!

It's almost like the processing power of another good PC- for 1/10 the price.

Edit: Hang on I've only got 1 PCIe slot anyway...

I would say not....
If you only have a 300W PSU, you are probably running on the ragged edge right now.
If you want to find out for sure, get a Killawatt or other power meter and check it. But I think you would fail if you tried to add another card without upgrading the PSU as well.

You might want to pick up a power meter to see how much power your pc is using.

If less than 200 watts you have room for more components if they're not too power hungry, and your power supply is a quality power supply.

It's alright my entire rig of machines is only ~400W all-in.

I'm trying to find cases that will support 4 GPU... (12 slots reqd?)

Is that all you're going to plug into the board?

Look up a LIAN LI PC-V2120A Silver Aluminum ATX Full Tower Computer Case.

It's got spaces in it - they need to be %20 (someone else had that problem a few days ago).

Yes cases can make a huge difference. I moved from a little Antec P-160(Yes the first P case made) to a Corsair 600T. Simply upping the case fans from 120's to 200's especially with that top vent 200 mde a good bit of difference on my motherboard and ambient air temps. My cpu may have dropped a bit, but nothing to take notice of, I think the biggest boon to temp drops I had was moving from a Artic Cooling Freezer 7 pro to a Tuniq Tower 120. It does better than the water cooling setup I have in my server. Still looking and thinking about going back to water though, just not sure if I want to invest any additional maintenance time at this point, considering how low temps are now. Another thing to try to is reseating your cooling with some newer better thermal paste. A5 or Ceramique depending on application is what I prefer.

So congrats on the lower temps, make sure you check for dust regularly in the HAF or your temps will start climbing back up!

Yep, HAF-932 cases are notorious for dust, Filters from DEMCifilters @ Performance PCs will help reduce the dust flow as their washable, Get a pair in fact, So that when Your first set is dirty the 2nd set can be slapped onto the case, So that the 1st set can be washed off with a dishwashing soap like DAWN by hand with a scrubbing sponge, then rinsed of when clean and then placed inside the dishwasher or in a dish rack to dry.

Fan guards.....
Still have to remove the airborne fluff that accumulates, but it keeps the tails and noses out of harm's way.

"Freedom is just Chaos, with better lighting." Alan Dean Foster

I'm trying to spec up my ultimate machine. I would like 4 GPU ideally. No compromise.

If you want to fit multiple GPU, say 3*, & each takes up the space of 2 PCI slots due to card-height, by buying a m/b with say 7 PCIe wouldn't you just be wasting them by them not being physically accessible? Can you get m/bs where the PCIes are double-spaced? Actually, surely you need the space of 3 - 2 for the card then 1 for an air gap.

I've seen a case with 9 PCI slots, so I guess given the above the max GPU you could fit would be 3. Discuss.
