Testing Methodology

For testing Micro-ATX and 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-Z68MX-UD2H-B3
Graphics Card ASUS GeForce GTX 560 Ti DCII TOP
(tested at stock speed and overclocked to 1GHz/overvolted to 1.13V)
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Kingston SSDNow V+ 100 64GB SSD
Samsung 5.25" BD-ROM/DVDRW Drive
CPU Cooler Cooler Master Hyper 212 Evo with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Plus 750W 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.

Thank You!

Before moving on, we'd like to thank the following vendors for providing us with the hardware used in our testbed.

    Seriously?

    You can buy a case today that will allow you to pop in a couple of high-end video cards without the need for even buying additional fans. A decade ago, you could hardly run one card without pulling off the side cover and setting up an external fan to blow into the case.

    But case design is largely based on mainboard format, and the rest of the components that go into the build. Those haven't changed much in 20 years, so the appearance and function of cases is going to remain similar. How I'll agree with you is to say the ATX format isn't serving us well today (particularly those of us interested in building high-end rigs). No mainboard form factor advance is something of a limit to advances in case design.

    Having recently assembled a build in a circa-2001 case that was collecting dust in my basement, I'm a bit torn. Tthere've been innumerable QoL advancements in case design; 120mm fans, more flexible fan mounting options, more general recognition of cable management, fewer hard edges, and so on and so forth.

    My old case works surprisingly well, but it was also an unusually expensive product at the time, and I searched high and low for it (and I don't even remember which company manufactured it). Even so, it's noisier than it needs to be simply because it uses 80mm fans. Cable management is nonexistent; I had to bundle up and toss every loose cable into the drive cages. I had to jury-rig my own fan filters.

    As others have pointed out, there's only so much true innovation anyone can impose on the ATX standard. If I have one complaint about current-day cases, it's that they all seem to come with a bottom-mounted PSU, which is fine if you plan to place the box on a hard floor or on your desk, but even a well-filtered down-facing PSU makes me extremely nervous when I'm placing the computer on a carpeted floor. Call me paranoid, but I'd like more options there.

    Dustin,

    I'm digging your reviews lately, but I really with you'd use an ATX sized motherboard instead of a mATX.

    With an ATX motherboard in certain cases, it may be cramped / difficult to access:
    - the SATA ports, when pushed up against the hard drive cage(s) (especially those mobos with SATA ports pointing sideways off the board)
    - the front case header connectors on the motherboard, when pushed against the lower portion of a case
    - the rear side of the 5.25" bays

    Even if you continue testing with mATX for consistency, would you please consider temporarily placing an ATX motherboard in each case, taking a picture, and commenting on whether any issues arise compared to an mATX board?

    *I really wish, not with. I don't have a lisp IRL.
  • anynigma - Thursday, February 14, 2013 - link

    I completely agree. With any case that fits an ATX motherboard, I want to know if I will have any issues with Sata cables and long graphics cards specifically, and everything crimson mentioned above as well.

    Dustin can you please follow up with an ATX space analysis, or as a bare minimum, a picture. as crimson describes above?

    Especially in these enthusiast cases like the Phantom 630 - who would use an mATX board in that thing?
  • niva - Thursday, February 14, 2013 - link

    And here I was thinking if it won't fit an EATX I'm not interested. Very valid point, test the biggest possible board the case was designed to fit.
  • Hrel - Thursday, February 14, 2013 - link

    Agreed, mini boards are for "normal" people.

    Part of the problem is that there's no major incentive to use an ATX board in general anymore. I have one in my desktop, but even if I used SLI I'd still only need four slots total. :|

    The clearance thing is admittedly worth considering. I'm not sure how well I can address this without trying to acquire an ATX board to test with, and then you have to keep in mind that some ATX boards are not as wide as others; meanwhile, our Micro-ATX board is actually *wider* than most mATX boards are. So when you're looking at the depth of the board and its proximity to the drive cages (including the side-oriented SATA connectors), that actually *is* what a conventional ATX board's clearance will be. Our mATX board is as deep as a standard ATX board.

    I'm pretty sure you guys are going to chop my head off and crap down my neck when you see what I'm planning for my super high stress testbed, but a lot of this is a matter of using what will fit the widest number of builds and allow me to get the most testing done.

    I'm rockin' a Sonata III with the popular GIGABYTE GA-Z68X-UD3H-B3 (12" x 9.6") and it's nearly impossible to access the SATA ports due to the hard drive cages - especially while my modest 6850 GPU is installed.

    Sonata III is an old, tiny case, but that's where I"m coming from, anyhow.

    Mini-ITX stapled into an engineering-sample 900D? ;-)
