Conclusion: The Only Game in Town
I keep feeling like Fractal Design is what would happen if Corsair were a European company. They share a lot of the same strengths, but they also share a lot of the same weaknesses, and that's fairly evident with the Define Mini. One thing Corsair consistently does better, though, is convenience. Their cases are typically much easier to build in and make a lot of allowances for the end user.
The Define Mini isn't a bad enclosure by a longshot. 21 pounds for a micro-ATX case seems a little bit much, but this is a lot of steel being used to dampen noise in addition to the acoustic foam. That makes the case both sturdy and capable of containing noise. The white trays and white expansion slots continue to be signature for Fractal Design and reliably sturdy and secure, the lighting is minimal and attractive, and it's frankly a nice case for the $99 price tag.

Where I think things start to fall apart for the Define Mini is its thermal performance. Liquid cooling in general is an excellent avenue for getting good cooling performance for internal components without generating a ton of noise. This is something that makes the Nanoxia Deep SIlence 1 such a strong contender, but unfortunately the Define Mini misses the boat. That wouldn't be so bad if the case was a solid performer with air cooling, but the included fans at least seem to be pretty inefficient. It's difficult for me to actually peg exactly why the Define Mini is such a weak performer where thermals are concerned, but it is.
I don't think all is necessarily lost with the Define Mini. It has some very strong points to its design and a smart builder could produce a competitive machine with it. The noise dampening does a fantastic job of keeping the system quiet, too. There are just missed opportunities here: a couple of allowances here and there for liquid cooling solutions could go a long way. Alternatively, better fans (probably ones comparable to Nanoxia's) or even bigger fans might be the order of the day. You're not getting a 140mm exhaust fan into this bad boy unless you widen the chassis by at least 10mm, but you can definitely get a pair of 140mm intakes in if you redesign the front, and those would help tremendously. The Define Mini is practically screaming for an R2.
Until Fractal Design comes up with a Define Mini R2, you're going to have to be okay with the trade-offs inherent to this version of the Define Mini. Alternatively, you may want to wait for Corsair's impending Obsidian 350D and see what they're planning to bring to the table where micro-ATX is concerned. The Fractal Design Define Mini isn't a bad case, but it does need some tender loving care, and it's not as great as it could be. It's the only micro-ATX case designed for acoustics, though, and if that's what you're looking for, the Define Mini's about the best option on the market.

I own this case. It's the perfect balance between size and workability. It's also very quiet and looks beautiful.TrackSmart - Monday, April 22, 2013 - link
I'm confused. Is this a typical size for a micro-ATX case? It is LARGER than my Antec Sonata III, which is a standard-size ATX case.Fractal Define Mini: 8.3" x 15.6" x 19.3" = 2499 cubic inches
Antec Sonata III 500: 8.1" (W) x 16.7" (H) x 18.2" (D) = 2462 cubic inches
I like the case. If it had existed 3.5 years ago, I would have strongly considered it for its quiet operation and nice design (assuming I was going micro-ATX). But it just doesn't fit the "mini" description very well, given that its the same size as many standard ATX cases.

The (now discontinued) Antec P180 Mini was the same way.What this design style does is let you have the bottom-mounted PSU in a case that is the size of a normal mid-tower, as opposed to the super-tall cases that have that feature and take full-size ATX boards.

The spots where it's bigger than old cases are all cases where changing design requirements have triggered growth to meet. Making it slightly wider is needed to route cables behind the mobo tray. The increased depth is mostly used putting fans in the front and to give them side intakes for noise control; with a removable drive cage (to allow really big GPUs and make connecting sata cables easier) taking a bit as well. It could have been made another Inch shorter but that would have precluded space for a top fan.The Define mini is a MiniATX case designed for building a high performance system and keeping it cool. The Sonata III 500's design was optimized for making a full ATX system as small as possible; having used other cases with just enough clearance from the drive cages to stuff the mobo in connecting sata cables with the board screwed down is a PITA and full length GPUs are difficult to impossible to fit..

Also, putting the PSU at the bottom instead of the top means you no longer have a big space at the top for optical drives to extend past the front edge of the motherboard without obstructing anything. Even without the fans and removable drive cage that would probably limit the case from getting any shallower.TrackSmart - Monday, April 22, 2013 - link
Thank you to DanNeely and A5 for the insights about case size and design. I can see the niche for this case based on your description. Basically, by shrinking the motherboard area you can better utilize the remaining space to allow for a higher performance machine in a (relatively) small package. If you are building something with modest power requirements (all of my builds), it probably doesn't matter, but for someone who is going to stuff an overclocked i7 and high-end GPU into the case, I can see where this would make a world of difference.DanNeely - Monday, April 22, 2013 - link
Broadly speaking I think the main target customer for this case is people who have historically built relatively high end desktops; but who have realized they don't need a full ATX board for a single GPU but who don't want the overclocking, etc limitations imposed by mITX.A5 - Monday, April 22, 2013 - link
Yeah, that's me exactly.antef - Monday, April 22, 2013 - link
I disagree that modern design goals necessitate these sorts of dimensions. My SilverStone PS07 is significantly smaller and still meets all the needs of a high performance system while keeping it cool. I'll go through each of your points:1) Width is the same between the Define Mini and PS07, so nothing to say there.
2) The SilverStone is only 15.7" deep and fits front fans, an HDD cage, and the biggest GPU you want just fine. There is no top fan mount but there is a top exhaust that you can direct the PSU's exhaust through. It's able to accomplish this since the GPU sits on top of the drive bay instead of trying to fit behind it. SATA cable access is fine but is especially easy when you remove the drive cage. If the case you used couldn't fit large GPUs then that was a fault of that particular case's design.
3) The SilverStone's PSU is top mounted which I don't see as a problem. This permits space for optical drives, and below that space for the motherboard, large GPU, front fants, and drive cage all in 15.7" of depth as mentioned above. You can also choose to not bother with optical drives at all, and remove the drive cage entirely and still be able to have 1 SSD and 1 HDD in the case.
Yes, it's a little tighter to work in, but today's systems can get away with a lot less components than in the past, giving you the ability to still keep the internals very clean and uncluttered. If you need more space, ATX is there for you.

Was interested in this article until I got to the case dimensions. Why not just go with a standard full-sized ATX case and stuff a uATX board into it? At 8.3 x 15.6 x 19.3 isn't that what's being done here?Frankly, the best uATX case ever made was the SG03 by SilverStone. Dimensions are a svelte 12.28 x 7.87 x 14.17. Moreover, if SilverStone had been forward thinking and dropped the legacy 3.5" form factor HDD drive bays from the design (stuffed in the bottom of the case) they could’ve shaved an inch from the height. Interestingly in spite its diminutive size, because the SG03 can be stripped almost to the frame, building a clean system is actually quite simple. I discovered that a little pre-planning of the layout produced a build that was almost a work of art. Also, the flow-through design made cooling the interior a snap. For the life of me I can’t figure out why SilverStone didn’t continue to refine the design (add a removable motherboard tray, dual 3.5” cutouts for 2.5” form factor mobile racks for a total of 4 HDD drive bays, etc). It would have become the preferred uATX case for the vast majority of systems builders.
