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.

Oh yeaDeath666Angel - Monday, January 23, 2012 - link
it just doesn't look very pleasing to me. Too much "1337 gamz0r pwn4g3".But that's just me. :-)

I'd be proud to own that. I'm honestly getting a bit tired of minimalism. There's not a whole lot of flashy "HEY LOOK HOW BADASS I AM!" cases that are also functional.Death666Angel - Monday, January 23, 2012 - link
Like I said, just my own opinion. Nothing more, nothing less. And "badassness" and "functionality" are also very subjective, I wouldn't give this case high marks in either category, much less so considering the price. :-)michaelheath - Monday, January 23, 2012 - link
Agreed. This case is aimed at the crowd of people who pay through the nose for features that accomodate the other components they paid through the nose for. As a person who lives within his means and requires no more case than what provides room for a modest gaming/entertainment machine, the Cosmos II is pretty overboard in most aspects, and I could put $350 to better use.Sabresiberian - Thursday, January 26, 2012 - link
Actually, I think this case is made so people like you can get swelled heads about how well you manage your money.I have a suggestion: give up your gaming/entertainment altogether. After all, it's really nothing you actually require. It's not only a waste of money because you spend it on things you don't need, it's even more a waste of money because it takes up your time, as well, time you could be using to make money instead of spend it.

At this price I honestly expected it to have an integrated liquid cooling radiator with dual fans not just holes for one. I like to buy high end stuff but I still expect to get my money's worth. This isn't it.ZeDestructor - Tuesday, January 24, 2012 - link
You'd like the Lian Li PC-A71F then. Its a big, black monser of a case that I'm planning to build my next rig in, complete with dual watercooling radiators...Tetracycloide - Wednesday, January 25, 2012 - link
The thing is, it's really not that flashy in many respects. They basically took an ostentatious design and painted it matte black. Why they wouldn't go with cleaner lines or a color scheme that better accents the lines it currently has I have no idea. I think it fails on the aesthetic front by trying to split the difference between minimalism and snazzy, never quite reaching either and attempting to appeal to two tastes that are fundamentally opposites.Tetracycloide - Wednesday, January 25, 2012 - link
Now that I've looked at it a little more and seen some additional close up shots from other review sites I've decided to change my mind. The case is flashy but in tasteful way although the tastefulness is largely left up to the builder. The mesh areas have a unique polygonal design layered into them that's almost fractal. With the matte black brush aluminum finish and the right color backlights (blue was the wrong choice IMO) the case could be very beautiful. Personally I'm thinking amber LEDs myself. Without backlighting many of the aesthetics of the case are lost IMO and it just looks like minimalism in areas that don't make sense because the other areas aren't very interesting without lights so the minimalist areas don't contrast with them enough. If you can imagine those areas backlit with LEDs it's a completely different case. The unlit pictures don't do it justice I think.
