Testing Methodology
For testing ATX cases, we use the following standardized testbed in stock and overclocked configurations to get a feel for how well the case handles heat and noise.
| Full ATX Test Configuration | |
| CPU |
Intel Core i7-875K (95W TDP, tested at stock speed and overclocked to 3.8GHz @ 1.38V) |
| Motherboard | ASUS P7P55D-E Pro |
| Graphics Card | Zotac NVIDIA GeForce GTX 580 (244W TDP) |
| Memory | 2x2GB Crucial Ballistix Smart Tracer DDR3-1600 |
| Drives |
Kingston SSDNow V+ 100 64GB SSD Western Digital Caviar Black 1TB SATA 6Gbps Samsung 5.25" BD-ROM/DVDRW Drive |
| CPU Cooler | Zalman CNPS9900 MAX with Cooler Master ThermalFusion 400 |
| Power Supply | SilverStone Strider Gold 750W 80 Plus Gold |
A refresher on how we test:
Acoustic testing is standardized on a foot from the front of the case, using the Extech SL10 with an ambient noise floor of ~32dB. For reference, that's what my silent apartment measures with nothing running, testing acoustics in the dead of night (usually between 1am and 3am). A lot of us sit about a foot away from our computers, so this should be a fairly accurate representation of the kind of noise the case generates, and it's close enough to get noise levels that should register above ambient.
Thermal testing is run with the computer having idled at the desktop for fifteen minutes, and again with the computer running both Furmark (where applicable) and Prime95 (less one thread when a GPU is being used) for fifteen minutes. I've found that leaving one thread open in Prime95 allows the processor to heat up enough while making sure Furmark isn't CPU-limited. We're using the thermal diodes included with the hardware to keep everything standardized, and ambient testing temperature is always between 71F and 74F. Processor temperatures reported are the average of the CPU cores.
For more details on how we arrived at this testbed, you can check out our introductory passage in the review for the IN-WIN BUC.
Last but not least, we'd also like to thank the vendors who made our testbed possible:
Thank You!
We have some thanks in order before we press on:
- Thank you to Crucial for providing us with the Ballistix Smart Tracer memory we used to add memory thermals to our testing.
- Thank you to Zalman for providing us with the CNPS9900 MAX heatsink and fan unit we used.
- Thank you to Kingston for providing us with the SSDNow V+ 100 SSD.
- Thank you to CyberPower for providing us with the Western Digital Caviar Black hard drive, Intel Core i7-875K processor, ASUS P7P55D-E Pro motherboard, and Samsung BD-ROM/DVD+/-RW drive.
- And thank you to SilverStone for providing us with the power supply.

I think it's probably the psu makers that have told the case makers to do this. that way the psu's burn out from dust long before they would if they were mounted at the top of the case. That way the psu makers can sell a lot more psu's than they would otherwise.seriously though, I agree 110%. I would never buy a case with a bottem mount psu, it is just not practical. Everytime I open my case I have to vacuum out a 1/4 inch of dust and fuzz off of the bottom of the case where it gets sucked in and settles. If a psu was on the bottom it would suck all that in which would not be good.

On a bottom-mounted PSU, the PSU does not either intake or exhaust into the case. (see gallery - the fan points down, not up into the case.)Any dust that gets into the case will not get into the PSU. Just make sure there is reasonable clearance under the case, so you get decent airflow...

I generally find cable management to be (at best) a wash, when deciding based on PSU mounting. There are difficulties either way.As for the bottom PSU mounting, if you purchase a case with a filtered PSU vent (almost all cases with bottom mounted PSUs feature some kind of filter) and clean it regularly (as you should any PC, to keep dust buildup to a minimum) then you should experience no adverse effects on PSU lifespan. And it's not like having it constantly sucking in hot air (when it's intake fan is inside the case at the top) is somehow better for it than taking some time every few weeks to dust off a filter.

I have it in my desk a few inches off the ground with filters everywhere that actually mounts it off the ground, but still despite diligently cleaning out the filter my Corsair HX1050 has dust in places no PSU should have ever. I am not a smoker, clean diligently and have filters over every intake in the computer, yet the machine gets soo fricken dirty so fast.These up and out case designs are just really bad, I love the way this NZXT looks, but just know it will be just as bad as my Corsair Obsidian. I really think there is a 3 inch no fly zone where dust hovers and gets kicked up from movement and the major flaw with these trendy up and out cases; is they tap directly into it. Would make a great design for an actual Air Filter, but not for cases.

Maybe you need to vacuum/sweep your floor more often. And yes, I have a bottom mount psu case, filters and have my case under my desk on the floor in a computer stand that gives it an inch of clearance off the rug. I clean the filters regularly and vacuum out the case periodically.danacee - Thursday, February 2, 2012 - link
that is always what people say when some new trend is found inadequate, never considering how much is too much.But yes I do weekly(I am a female and am sensitive to dust) and no, my case does not get stuffed full of dirt. The problem is how much more I need to clean out the fricken thing because some idiot thought it was a good idea to give it the airflow of an upright Hoover.
FYI I had an older front back out based airflow case and the thing in the very same stop and despite heavier use, never collected dust at the same rate. Also my primary work machine is a Mac Pro, same story.

i have bottom mount psu - i just installed it fan side up so it sucks air out case and out back of psu. surely thats the ideal situation...and to the tin foil hat guy who think its conspiracy to break your psu - lol enjoy life.

Is there a reason you don't just flip the PSU around so that it draws the intake air from inside the case? To me it seems like up or down don't really matter in most situations, for most people. In the few where it matters, it matters for people smart enough to know which way to go.zero2dash - Wednesday, February 1, 2012 - link
Funny, I've never heard of a bottom mounted PSU "blowing up". In fact, any time a PSU "blows up" it's because it inherently is flawed; not because of how it was mounted in a case.Either turn the PSU upside down, take your case off the floor, or buy one of the dozens of top mounted PSU cases still widely available.

As massive as some PSUs have gotten I think mechanical constraints are part of it. You need solid support to hold it in place on the top now on the bottom you can just use the existing metal.A case this huge could have it mounted sideways on the bottom though and avoid the carpet clogging and worst of the dust sucking problems in the process.
