For testing full 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.
| ATX Test Configuration | |
| CPU |
Intel Core i7-2700K (95W TDP, tested at stock speed and overclocked to 4.3GHz @ 1.38V) |
| Motherboard | Gigabyte GA-Z77X-UD4H |
| Graphics Card |
ASUS GeForce GTX 560 Ti DCII TOP (tested at stock speed and overclocked to 1GHz/overvolted to 1.13V) 2x NVIDIA GeForce GTX 580 in SLI (full fat testing only) |
| Memory | 2x2GB Crucial Ballistix Smart Tracer DDR3-1600 |
| Drives |
Kingston SSDNow V+ 100 64GB SSD Samsung 5.25" BD-ROM/DVDRW Drive 3x HGST DeskStar 3TB 7200-RPM HDD |
| CPU Cooler | Cooler Master Hyper 212 Evo with Cooler Master ThermalFusion 400 |
| Power Supply | SilverStone Strider Plus 1000W 80 Plus Silver |
Each case is tested in a stock configuration and an overclocked configuration that generates substantially more heat (and thus may produce more noise). The system is powered on and left idle for fifteen minutes, the thermal and acoustic results recorded, and then stressed by running seven threads in Prime95 (in-place large FFTs) on the CPU and OC Scanner (maximum load) on the GPU. At the end of fiteen minutes, thermal and acoustic results are recorded. This is done for the stock settings and for the overclock, and if the enclosure has a fan controller, these tests are repeated for each setting. Ambient temperature is also measured after the fifteen idle minutes but before the stress test and used to calculate the final reported results.
For the "full fat" testbed, the GTX 560 Ti is swapped out for a pair of GTX 580s, and three hard disks are added to fill out the case.
Thank You!
Before moving on, we'd like to thank the following vendors for providing us with the hardware used in our testbed.

The 3.5" cages are stackable that's good... my question is can you add an extra one (provided that corsair will sell you one)?garadante - Tuesday, September 24, 2013 - link
Sure looks like it, as that's what they offered with the 900D. Perhaps the drive cages are even identical? I know the 900D came with 2 or 3 drive caves but you could have 5 installed total I think.Grok42 - Tuesday, September 24, 2013 - link
Not my choice of case for other reasons but I have to give them a lot of credit for being able to stack cages and selling additional ones. Now if they would only sell 2.5" in addition to 3.5" cages.BillyTheBigBone - Friday, February 14, 2014 - link
yes you can. I ordered one from them.Alan G - Tuesday, September 24, 2013 - link
In this day and age, two USB 2.0 along with two USB 3.0 ports on the front panel? Why?DanNeely - Tuesday, September 24, 2013 - link
At $159 "it's cheaper" isn't a good excuse; but I'm sure that's still part of it. Probably Corsair's explanation if asked would be that a lot of mid range mobos still only have a single USB3 header and very few people would be plugging in 3 USB3 devices at once anyway.IMO the better option would be to include either a short adapter cable to connect a USB3 cable to a USB2 header, or to wire the second connector onto the cable itself like the dual connector cable you often see on front panel audio. I'd prefer the first option because it lets people with 2 USB3 headers toss the adapter in their junkbox and have a cleaner build.

What else is going to go there...LB-ID - Tuesday, September 24, 2013 - link
I was doing a fresh Win7 install on a new computer the other day, couldn't figure out why the keyboard and mouse kept going dead during the install process. Figured out it was lack of USB3 support on the OS, so was very very happy to have a couple of USB2 ports on my Nanoxia DS1. Sometimes it pays to have backwards compatibility available...Threnx - Tuesday, September 24, 2013 - link
I would like it a lot more without the gaudy window. It's 2013, who still thinks those look good? They should go the way of lighted LED fans.flemeister - Tuesday, September 24, 2013 - link
Not you, evidently! =DI love the look of a clean side panel window, free of any ugly fan grills. And anyway, it's 2013, where an all-black interior is now pretty much standard for ATX cases. More and more PSU's come with decent looking cables, whether just black insulation on the wiring, or braided sleeving installed by default. And it's *very* easy to find nice looking motherboards and video cards now, compared to ~2009 and earlier. There's been no better (or easier) time to show off the guts of your rig! =)
