5 out of 5 eggs

Pros: - One of the smallest, if not the smallest, mATX case you can buy
- Fits a full-size graphics card (<= ~10.5 inches), though it can be a real pain to install it
- All nice aluminum, no plastic to be found. Feels classy and sturdy, while still being very light.
- Power led is not overly bright
- No needless 5.25" bay or extra 3.5" bays
- Fits full ATX PSU

Cons: - Wish power LED were white instead of blue; I may change it myself one day
- Cooling ability isn't great, but honestly it won't make a noticeable difference in your maximum achievable overclock. I'm running an overclocked 4770k and a GTX 770 in it and temps can break 90C when stress-testing, but it's fine in practice.
- Like I said above, installing a full-size GPU is possible but can be a real pain angling it just right to get it into the case. No other portion of the build was particularly difficult, though.

Other Thoughts: You probably should get a 92mm heatsink like I did instead of a 120mm if you want to be sure you can use the 3.5" bracket.
I fit 2x 3.5" HDD and 1x 2.5" SSD in it no problem. Just taped the SSD on top of the bottom-mounted 3.5" HDD.

4 out of 5 eggsNice case, but hard to work with

Pros: *Excellent build quality, nothing feels cheap about this case. No flexing of the panels
*Modern design and layout, no optical drive bays
*It's about as compact as you can possibly get while still allowing +120mm tall coolers
*Comes with an incredibly quiet rear case fan (label says 25.9dB), although it does not move a lot of air
*Front LED/power button is bright enough to see in a lit room, but does not cause a "flashlight" in the dark. Also has a second led for an hdd indicator

Cons: *There is not very much room inside this case at all when dealing with a full sized mATX board. If you have edge facing sata plugs, use L-connector cables off the board; straight ones will literally be jammed up against the front and will not come out without removing the board. The one thing that will give you huge headaches is the bracket on the bottom right corner that holds the USB/audio front ports. This thing is destined to get in the way of mobo and GPU during installation.
*The included hard drive bracket (the swiss cheese looking cover over the PCI area) might not work for some with tall coolers. My Hyper212 heat pipes just barely poked into the space that would be filled by the drive. Drives can be mounted to the bottom, but in the process they block most of the vent. A better solution would have been brackets behind the front panel to give the option of mounting there.

Other Thoughts: This is a rebranded 'Jonsbo U3' in case you want to do a search to find more reviews or pictures of it. I've been waiting for a case like this for a long time. Quality materials, and as small as you can possibly make it while still being able to support a tall cooler. No support for a dozen hard drives or 3 optical drives or any of that stuff. I had a TJ08e and despite popular opinion, I hated it for a variety of reasons. The U3 is much more to my liking, but it really made me question my obsession with small pc cases. On several occasions I put everything together only to find the last component would not fit. Every... single... part had to come back out so I could try again. Finally I wised up and did a dry test fitting so I could make a mental note which order stuff had to go in. Cable management is definitely doable, but requires planning. I actually went so far as to remove the rear fan switch (it doesn't help much with the stock fan anyway) and desolder the front audio header cable just to free up space and keep me from having to find a place to hide them.

I could only recommend this case for full sized mATX users if you have a bit of experience, patience, and small hands. If you have a smaller mATX board or a M-ITX and aren't using a large cpu cooler, you don't really have to worry.

Build:
ASrock z77 Pro4 M
EVGA GTX 760
CM Hyper 212
1x 2.5 ssd
1x 3.5 hdd
(3.5" hdd mounted to the bottom, 2.5" mounted on top of it with double sided tape. Since my cooler blocked the hard drive bracket, there were no other possible options for this setup).
