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!

    Looks good perfect for my new build.

    I love Antec Cases. I could really use this for the next rig I put together with my bros so we can LAN. :]

    Interesting design and the solid front is similar to my Solo case I've been I've been running my Core i5 660 in for a year. But recently i got to install an Antec 300 Illusion case and I have to say I really like it. While the 300 Illusion does not have and USB 3 ports up front it's not a big deal as most motherboards don't have USB 3 headers yet so plugging the USB 3 device in the back is ok for now, The primary reason I prefer the 300 Illusion case is the front is all mesh and with the 2 120mm fans you can pull in major air to keep the computer cool. The rear 120mm and top 135mm fans blow the warm air out. Setting the front fans to low speed and the rear fans to medium speed makes for a quiet but cool computer.

    Pork chop sandwiches!

    This P280 really looks like a nice piece of equipment!

    Now I feel a bit sorry I bought a new case a few weeks ago. It was an almost used Themaltake Xaser V - an older case but I got it very cheap and it still is way better than what I had before. This one seem to be well worth the price increase, though. Way to go, Antec! :)

    Don't think I'd buy one, but I'd love to win one!

    Great review and read. Makes me think its time to get a Antec case again, Miss my old super lan boy!!

    The case look so good, I have the P182, which I modded to my liking. The main reason that I like the Antec dual chamber is that I can hide my pump.

    Finally Antec adds a forward top fan position. Their prior cases of this type always had one fan in the back. As if no one would ever want a top intake. It is disappointing that they only have spots for 120mm fans up there. Spaces for two 140mm fans would carry the forward fan further forward, so that more of its output can feed the face of the cpu heatsink intake fan.

    The forward-facing IO ports are a blessing for those who must put their case under a shelf.

    I love that they went whole hog on their cpu cooler window in the motherboard tray.

    But I wish they had put room for four slots in their 5.25 bay: some of us put intake fans there.

    Finally: why oh why is there a rear grill? With no grill, if you run all intake fans you can let air quietly escape -- no fan needed.

    Otherwise, decent case.
