Testing Methodology

Part of the reason we took so long in getting new case reviews up on the site is because we decided to go back and revise our case testing procedures. Moving forward we're standardizing our testing methodology in a way that will hopefully feel more concrete and useful than our previous reviews did. I'm going to take the opportunity to break down how things are going to work for this and future reviews, but note that these procedures aren't set in stone. Anand stressed to me in conversation that one of our greatest assets is essentially the mountain of free feedback we get from people who comment on our reviews, and I agree with him. We pride ourselves on being fairly agile and adaptable to the needs of our readership, so if you feel there's something we can change and it's feasible, rest assured that we do listen and will at the very least take it into consideration.

First, we've standardized on two testbeds: a Mini-ITX testbed that's low-powered and doesn't generate too much heat, but isn't too miserly either, and a full ATX testbed that's indicative of the high-end of what most of you are running. Since this review uses our Mini-ITX bed, I'll save discussing the full ATX one for that review. The essential thinking here is that a Mini-ITX board can be used for Micro-ATX builds like this one without sacrificing much (we're not testing multi-GPU scenarios for cases this small since they're seldom designed for it), but we still use a processor that produces enough heat to merit thermal testing. Before I go any further, it may be prudent to just lay out the hardware we're testing with:

Mini-ITX/Micro-ATX Test Configuration
CPU Intel Core i3-530 (73W TDP)
Motherboard Zotac H55ITX-WiFi
Graphics Card Intel HD Graphics (IGP)
Zotac NVIDIA GeForce GTX 580 (244W TDP)
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Slimline DVD+/-RW Drive
Kingston SSDNow V+ 100 64GB SSD
Western Digital Caviar Black 1TB SATA 6Gbps
CPU Cooler Zalman CNPS8000A with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Gold 750W 80 Plus Gold

The Zotac motherboard is included as one of the most fully-featured Mini-ITX boards available, and it works with the Core i3-530 we had on hand. That i3-530 is also fairly typical of what to expect in smaller builds. From there, the Crucial Ballistix Smart Tracer memory has a unique feature particularly suited to our needs: it includes thermal diodes that can tell you how hot the memory is running. The SSD is used to gauge how easily a 2.5" drive is installed and to provide a stable baseline, while the Caviar Black gauges how easily a 3.5" drive can be installed and gives us a secondary reference point for drive temperatures. The Zalman cooler is quiet, low-profile, and effective, giving us an alternative to the Intel stock cooler. And finally, SilverStone's power supply is modular, small, and efficient, making it ideal for case testing.

Of course, the GeForce GTX 580 is going to raise some eyebrows. In this instance, we wanted a video card for case testing that would push thermals without overpowering acoustics. Not all cases we test with are going to support it, but enough are to warrant its inclusion. As a result, Mini-ITX and Micro-ATX systems are tested in two configurations: with and without dedicated graphics.

Moving on, 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 a silent apartment 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.

Finally, 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.

Thank You!

We do have some thanks in order before we press on, though:

    I disagree with the people who said it looks hideous. Surely their comments are hyperbole? I'm not saying it's beautiful, but with such a simple, unadorned, rectangular enclosure, the worst thing I could say about it is that it's boring. Not a deal breaker for me, ESPECIALLY for a well cooled, microATX case where the options are severely limited to begin with.

    It's clear they're aiming for quiet by keeping temperatures low rather than any acoustic dampening. In that respect, I wouldn't use this case for my primary gaming desktop, because the graphics card will always be loud. However, this would make a great HTPC case, where the slot-in aesthetic works well and you're likely to use passively cooled components that don't generate noise to begin with.

    Also, good job on the review and I'm glad to see the revamped testing methodology. Good case reviews are hard to find, but they're so vital for system builders, professional and amateur.

    I agree, it is definitely not hideous. However, I honestly would not want my pc looking like that. As much as I admire the internal engineering, the design is more suited for a refrigerator (it even has the snowflake...)

    I put this case in my cart on Amazon last night and was debating pulling the trigger. I really like the looks of the silver model. I think I am going to buy it right now.

    I already see my first mod. I will replace the plastic vent at the bottom with an acrylic window with a few holes for ventilation. Mmmmm case moding gets me excited.

    At first i thought this would be like an upgrade of the already awesome FT02 case, but this (FT03) is a totally new category (mini,micro), completely different than FT02.
    Pretty weird changing the fortress line to another category.
    By the way does that mean there won't be any upgrade to the good old FT02?
    The idea of having the whole backpanel as a top panel is just awesome, it really helps a lot, and also moving cool-hot air from bottom to top is pretty good following the natural flow of cool-hot air.
    I have the FT02 and i believe it's the best case of all i've tried so far (even better than my beloved p182),
    i hope the FT03 is as good, though too limited/restricted for my needs.
    All in all, good review for what seems to be a nice case for its class.

    I would love to see what it looks like with a slew of cabling coming out of the top. I feel like it would be pretty congested up there with USB, DVI, networking etc.

    Great review, i was really curious for an in-depth one, when i saw the video at CES2011.
    Can't really be sure about the materials used though, as other users mentioned, plastic parts don't justify the price.
    I got a minor complaint and not just from this review, but from all the media that are reviewing hardware.
    This is a piece of hardware with half (at most) the aluminum of a normal ATX case. Yet, it's priced @170$ and in Europe will be @170€. And it's editor's choice, meaning that you are "promoting" it indirectly. So 170$ is ok? Do you also encourage, that a normal aluminum case should cost, what, 300$? I think not, but, being a media you can direct the prices for manufacturers, yet you don't do anything about it.
    All you are saying to the public is ok, it's a great one. But i doubt if anyone has e-mailed to a manufacturer about it's pricing politics.
    400$ Graphics card, 170$ a case, 300$ Cpu, 300$ MoBo, do the maths. 4 years ago the same (proportionally) PC would cost about half as much, wonder why?
    You are a part of it, you should.

  • MilwaukeeMike - Thursday, April 28, 2011 - link

    Why does a large fries cost more than a medium?
    Why does a large t-shirt cost the same as a small?
    Why does a pack of 25 blank DvDs less than a single movie?

    You're paying $170 for a case, if you want to buy raw aluminium and make your own to save some $$$, go right ahead. If you think it should cost less because it's smaller, then please direct your anger toward those price-gouging tablet PCs.
  • Aengex - Thursday, April 28, 2011 - link

    Great arguments there, but they do not apply to what i'm saying.
    In short, i would like to see consumers and media ( who play a major role) boycotting products that do not worth the money.
    Hopefully, many companies will then change pricing policies (not politics as i wrongly mentioned above).
    Sure i do like i.e. Apple, but as a consumer, don't agree with their prices. And i don't want other companies to follow that path.
  • JarredWalton - Thursday, April 28, 2011 - link

    "Worth" is all relative. Saying we should "boycott products that aren't worth the money" is the same as saying, "only buy products that you feel are worthwhile." Everyone already does (or at least should do) exactly that, but where you're going astray is in thinking that what you like or dislike is the only metric. I think MacBook Pros are well-built laptops, but I would never buy one. Millions of people disagree with me. Dustin feels this is a well-built micro-ATX case that has some interesting features and that certain people will like it a lot; others disagree.

    A thin aluminum case is cheaper to manufacture than a thick aluminum case. R&D also costs a lot of money, so doing testing to make sure your mATX case is capable of supporting up to two GTX 580 cards in SLI isn't "free", and that carries over to the price. Making an ATX case that can accommodate two high-end GPUs is practically a no-brainer by comparison. I haven't handled this case in person, but in the past SilverStone has typically used much thicker aluminum panels than the competition, and the reason you're paying $170 for this case is for the R&D, the four 120mm fans, and the overall build quality and aesthetic.

    For the record, a Bronze means a product is "very good". Silver would be "great", and Gold would be "exceptional". Giving this product a Bronze is our way of saying, "this is a very good micro-ATX case that will appeal to many users in the targeted market; however, it has flaws and will not please everyone."
