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!

    How about a case shoot out with a difference.
    How about the Fracal Design Arc Midi vs the BitFenix Merc Alpha?
    Except spend $60 on upgrading the Alpha. Use the money to put in better fans and such.

    Now hear me out before people jump on me.
    For a lot of builders they enjoy the act of building and improving. So it would be interesting to see if a hobbiest would be better off modding the Alpha vs buying the Midi.
    You can do the same thing with the Midi vs a more expensive case

    I like the case. I might recommend it or the smaller brother, Arc Mini.

    However, I personally don't understand the obsession with:
    a) tool less installation in general and
    b) tool less installation of drives especially.

    I don't assemble / tear apart my cases that it is a big concern. And having actual screws to tighten gives me a better feeling. Depending on the approach, tool less drive assembly might also inhibit my ability to install non-drive stuff in the cages, for example water cooling equipment, fan controllers, back planes etc., when they use non-standard holes.
    This stuff may be important for big OEM who assemble millions of PCs. But for me as someone who assembles PCs for myself and friends and family, I see no reason to go with tool less, if I can avoid it. :-)

    But a good review overall! And I like that you guys are tackling a lot of normal-budget cases. I don't see the appeal in huge 200 to 300USD cases that can house 10 HDDs and 4 GFX cards. :D

    I'm sort of glad the noise levels were only OK, it makes my purchase of an Antec 902 feel I little bit more justified.

    plenty of space for a mid tower build and was easily one of the most pleasurable experiences I have ever had when actually putting the computer together, I can't really recall any instance where I was stumped or struggled on how or where i was going to route my cable management

    moved the top 140mm fan to the front to have dual 140 intakes and make room for the 240mm rad of the H100, and added an aftermarket NZXT 140mm to the bottom as an intake

    right now my biggest gripe is the side panel which allows for either at 140mm or 180mm fan could be improved as the 200mm round fans have mounting holes that are actually in between the 140mm and 180mm dimensions they provide and thus are simply not an option to install without some sort of mod.

    A filter would also be nice for the side panel otherwise I'm more inclined to use it as an exhaust but that would likely upset positive pressure

    all in all it has easily been one of my absolute favorite cases to work with thus far, I'm tempted to buy another and convert some old systems

    That is one very nice clean build. I think I can spot my favourite Gentle Typhoons on the Rad.

    Do you need that many intake fans? Personally I would be tempted to pop in a thick 140mm rad at bottom (or front if you are not using the drive cage) a cool the GPU and CPU. But that is the problem with water cooling - once you start it is difficult not to tinker

    I finally swing to Fractal Design after reading this review and seeng the build quality of the Arc Midi, and reading several other reviews,

    but I was looking to build a silent system, and I also think about microATX system, so I decided to get the Define Mini, there's a "bug" in the case regarding multi-GPU setup, but since I'm not thinking of going multi-GPU (budgetwise), I decided to get the Define Mini.

    When are you guys going to review the Xigmatek cases?
    They a lot of midi towers that are very sleek and considered to be big value.
    Cheers,
    Kevin

    Just another el cheapo paper thin case. I have not seen a good case since wave master had like 3mm thick aluminum everywhere.
  • snapdrag0n - Sunday, October 9, 2011 - link

    CM Storm still the best pound for pound at this price range.
  • Bazzatron - Tuesday, October 11, 2011 - link

    The Fractal Design Define R3 is about the same price here in the UK. (About £75)

    Weighs a ton - combined with a "Be Quiet" PSU is the most silent PC I've ever built

    Very impressed with this case
