Testing Methodology

For testing Mini-ITX and Micro-ATX cases, we use the following standardized testbed in a stock configuration as well as with add-on graphics cards to get a feel for how well the case handles heat and noise. As we've retired our Micro-ATX board from the testbed, Micro-ATX enclosures will be using the Mini-ITX testbed.

Mini-ITX Test Configuration
CPU Intel Core i3-2120
(65W TDP)
Motherboard Zotac Z68ITX-A-E
Graphics Card Intel HD 2000 IGP

Zotac GeForce GTS 450 Eco (dedicated)

ASUS GeForce GTX 560 Ti DCII TOP
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Kingston SSDNow V+ 100 64GB SSD
CPU Cooler SilverStone NT07-1156 with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Plus 1000W 80 Plus Silver

Each case is tested with just the Core i3's integrated graphics as well as with a discrete graphics card. The system is powered on and left idle for fifteen minutes, the thermal and acoustic results recorded, and then stressed by running four threads in Prime95 (in-place large FFTs) on the CPU, and OC Scanner (maximum load) is run when the dedicated GPU is installed. At the end of fiteen minutes, thermal and acoustic results are recorded. 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.

We try to maintain an ambient testing temperature of between 22C and 24C. Non-thermal test results aren't going to be directly comparable to the finest decimal point, but should be roughly comparable and give a broader idea of how the enclosure performs.

Thank You!

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

    I have this case, it has a high build quality and very quiet - not the best cooling in stock form, true, and I think that is due to weak intake design and the damping material acting as insulation. I get little airflow even without the middle drive cage installed, my RAM gets pretty toasty - definitely been the source of a few crashes. I have a Corsair H70 (blowing out), a triple fan GTX670, and fanless 500W PSU which all run within comfortable temps. My system is just about silent under the desk which was my goal, I think with one more fan the system would run plenty cool but as you will see in my next comment the spot where a fan would do the most good for me is unusable.

    One design flaw, at least for me, is the location of the side panel fan cutout - it's too far towards the back of the case and because of this I cannot put a fan here as it interferes with my H70 radiator. If it was a little farther forward this would not be a problem and would also put it in a better location to cool the mobo.

    Two comments about the review - first, do you REALLY care about built-in standoffs? IMO it's a tiny "upgrade", it saves about 2 minutes max the first time you build a machine. Second, I was able to route all of my cable behind the mobo from the included fans & controller... barely. It IS doable but you may need to cut some wiring sheaths and get creative with routing.

    At $100 I think it's great value in terms of build quality, materials, etc - I can't believe I've been buying $50 junk boxes all of these years when for not a lot more the boxes are way nicer. Would love to see a revised model that improves cooling and cleans up the front design with a more minimal drive setup.

    Bought a Fractal Design R4 Mid Tower 2 days ago. This case is a jewel. Heavy, less sensitive to vibration. Everything in this case has been thought carefully: cable management, filter, noise reduction, paint job, even down to the screws and the metal rulers hiding expansion card slots. It is way better than more expensive case from Antec and Cooler Master. This company should make more marketing. Even better, it look nice! Even my wife finds that it looks beautiful.

    I have the Define Mini. It's a nice case. It's heavy (sturdy) and very quiet. Having to manually adjust the fan is a bit annoying (and believe me, you will want it on max for gaming and min for anything else). It takes a stock 680 GTX so it handles a longer card than the specs specify. I added a second front fan as I have 5 HDDs inside (4 in RAID 5). LED is too bright (lights up the room in standby with blinking blue) and no HDD LED unfortunately.

    It is for mATX motherboards but it is not small case, my other mini tower case with ATX board inside is only about 1 cm taller than Define Mini, including standoffs. Only cons with this case is irritating bright blue LED (I assume also red LED in white cases), it burn eyes, nothing minimal here as article suggest. Don't need to mention LED suspend mode blinking or bright blue LED when watching films in dark room.
    Overall, well built, quality case.

    My big problem with my Fractal Define Mini is that I bought it hoping to go to a 'smaller' computer, but I didn't really check the dimensions before I did it versus what I had. I was coming from an Antec 300 and I wanted a bottom power supply intake, some sound deadening, and a few tool-less amenities along with downsizing from an ATX board in that build to an mATX board in the current build. It only cut two inches off the height, but got an inch wider and over an inch deeper in the process. So while I can understand that these builds are "small" in comparison to things like 800D and HAF X, they still aren't 'small' when you compare them with more 'budget' full-ATX offerings. I feel like all I lost in the transition was the flexibility of three extra slots while gaining some noise reduction at almost twice the cost. I also wish the door opened wider, and my front intake fan has starting buzzing against the frame after only a few removals for cleaning.

    I used a Define Mini for my most recent build. Totally silent under my desk. Very sturdy and looks good. I have been very happy with it. Only pet peeve is I wish the front door swing were reversible (PC sits to my right but door swings open to the left).

    Dustin, it would be nice if you'd make sure to include a picture of the final rig as tested, with GPU, so we're clear how you set it up. I have left the middle drive cage in rotated to funnel air flow over my CPU. Did you try that out and see any difference?

    I was just talking about how good this case was. I got it for my girlfriend in White because the Corsair case is still too pricey right now. This case was all sold out and i had to order the one with a window kit because i liked it so much. I have used it in 3 builds just this year. Great Case. The front door likes to act up, but if you are a veteran builder you will have the parts on hand to reinforce the mechanism that catches the door and makes it stay closed with a click.
