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:

    Dustin your reviews are spot on and very detailed. Keep up the good work.

    Where's the P280 Mini? This would be money in the bank.

    I have an Antec Sonata II and Sonata III and love them both, because they are so quiet and elegant looking.

    But there are a few things wrong with these cases. The cable routing is non-existent. The motherboard tray doesn't have a CPU cut out for mounting after market coolers. The back panel isn't removable. And changing out hardware is a royal pain in the behind.

    Fractal Design turned my head today, because I discovered they make cases that incorporate all this functionality and look elegant at the same time. The ARC Define MID Tower, Define R3 and Define Mini are everything I’m looking for. The drive sleds look like they were taken right out of my Sonatas and painted white. I can’t believe it! This is where Antec should have taken their Sonata line up in the last few years. What happened Antec?

    The P280 is a step in the right direction for Antec and the design incorporates changes that people want to see nowadays, but the case is way too big for my taste. Shrink it into a P280 Mini and it might just win me over.

    My first build was with an Antec case. After that I tried a couple other brands but my favorite by far was Antec. This new case looks like it holds to excellent engineering that they started with and does it one better.

    I have no idea, why did they put only two in the top? Why not three? There is enough place for them and having ability to place 360 rad there would be very nice!

    I have a question for reviewer: what is the gap between side of the HDD cage and left door? I placed pump there in R3 and the gap is large enough to conveniently pass the tubes there. I am wondering if this could be done in this case too?

    Considering the two year wait since P183 I'd say somewhere between a single or double.

    - I'd love to see 140mm capabilities for the fans

    - Can't see from the pictures, but I'm guessing the power and reset button on the top may be too easy to get pressed by accident.

    - Where their main competitor provides covering for unused fan openings, it seems like a pretty big oversight for Antec not too.

    - Not exactly sold on the pointy corners at the top of the front door. Would at least like to see darker color door option to de-accentuate.

    The big selling point for me is the 170mm cooler clearance (I think Define R3 is published as 165mm).

    The pricing I've seen online ($120-125) does seem a medium premium for a medium increase in quality over the R3. Not sure which way I'll go, but the good news is the R3 price online does seem to have just dropped back to $99 (from $109).

    I have owned a couple of P180's, which I liked. Except for the dual chamber - a real pain.

    Although it's a bit heavy, if it helps keep it quiet then that's OK. I especially like the connectors placed at the top front of the case for convienience. And the interior is a rock-solid layout too.

    Antec installed a vent for the PSU. With a filtre no less! Good on them.
  • infoilrator - Wednesday, November 16, 2011 - link

    Changes (updates) were needed and it looks like all "issues" have been more than addressed. I like it.
    Design and Egineering were looking ahead, and succeeded.
    Workable, buildable, quality, longevity.

    now that I've moved all my HDs out of my main workstation and put in an SSD, i'm ready for a new case that will help reduce the noise even more. looking forward to playing with this one.

    22.3 lbs. seems rather light.

    Back in the late 90's I owned a computer shop and the best decision we ever made was to use Antec cases and power supplies in all of our system builds for customers. After mucking about with cheap PSUs in enclosures (very common in those days) that used to tear your hands apart worse than your neighbours cat, I hardly remember an Antec PSU coming back for warranty! Years later my shop is long gone but I am forever keeping tabs on Antec and still own a number of their fine cases... something like the P180 series and now this new P280 will only continue to pique my interest... thanks Anandtech and Antec... I love you both!
