Easy my favorite case to work with even tho it was literally the most difficult system to assemble at this considering the size of this I'm checking that as a pro not a con because i managed to cram a full i7 8700k water cooled on a pro z370 overclocking mothermoard(itx) and a full gtx 1070 sc2 and a full sized atx power supply and a full sized 3.5in hdd to complement my hidden m.2 nvme ssd all inside a case that is less than 15letters its ridiculous how cool this thing stays at a full 5.2ghz overclock with a gpu and ram overclock and still quiet enough to not hear it unless u put ur ear right up the the front panel its crazy and iv been recommending this case to all my clients when that consider this form factor.i just ask them if that want to experience what it's like to be able to fit a full spec cutting edge gaming rig into a small backpack and that's it there as sold as I am....update about a year later...still highly recommend this but I must emphasize this is not a test bench its is simple pressed steal so if you take this apart once a week you will stripe the back screw holes out and may end up breaking the very thin plastic screw mounts that hold the front panel in...I must insist that anybody building in this should plan ahead vigilantly and plan on building a usable system ment to be deployed and just work for a period of time and dont make the mistake I made and have this thing opened up a dozen times within the first 2 weeks not because it didnt work well it worked great until i stripped all four case screw mounts out and broke all 4 screw lips for the front panel while tinkering with difrent componets but I managed to repair this with a little bit of epoxy and some small nut and bolt sets and now it is much sturdier and has reinforced screw points😎...but my forgiving messaging aside it would be realy great if they made this with a simple folded sheat mettal back so there is at least minimum reinforcement and maybe mettal screw mounts on the front panel instead of thun plastic other than those to tiny things this case has been tremendously impressive especially considering it's a basic metal box nothing more so I know the manufacturing costs arnt so high they can do these simple revisions and still sell this for around the same 55 to 60 us

I would have done it a bit differently, and I did, but it still deserves 5 stars. It's designed to be as small as possible while still using standard size PC parts w/longer video cards. Vents are 'almost' all in the right place.
At first I had just planned to air cool my 6600, since it was only a 65 watt cpu, I figured I could just mount the PSU fan down and blow the heat from the cpu. I soon realized my PSU wouldn't last long with that kind of heat coming out of it. The power supply is almost always the weak point (capacitors) in any electronics. The cpu was hitting as high as 65 C, yet still slowly creeping up. Had to figure something else out.
I flipped the power supply fan up which then takes air straight from top ventilation keeping the PSU ultra cool, 'cept now I'm hitting temps of 70 C, and that was only as long as I dared run it under load, since it was also slowly creeping up. MOBO hit 60 C.
I then resorted to a liquid cooler, but I still didn't feel comfortable running it for long periods, since it seemed like it was still creeping up in temp. I drilled extra intake holes as shown in the blue rectangle and modified the top plate intended for mounting 2x 2.5 inch drives for a fan. There is too much heat at the top to mount drives, so I put them just above the intake on the side of the PSU. 2 SSD drives together now stay nice and cool.
I cut an opening to vent the fan I now had mounted on the top with a grill.
Using 4 pin fans where I can control speed I've set it to idle whisper quiet, and not ramp up until under load. My temp ranges are 40 C idle, and 60 C under load. The best part is it stays there regardless of how long I play.
I am not saying this case is inadequate for cooling, but maybe better suited for less powerful builds. It stays cool for everything other than high end gaming. I wanted to figure out how to keep it as cool as possible since heat is the silent killer of electronics. Cooler = lasts longer. I messed up initially using a 3 pin fan for the radiator so there was no fan control and it just stayed at 1500 rpms. Now I have a 4 pin that can also move more air. This might have solved my issue initially without the need for a top fan, but I am still happy with the mod. Blowing heat from the top is always a good idea.

Easy to assemble and fits a full size ATX (assuming you have an AIO for the CPU). Really only spot for 1 120mm fan, but I have no issues with cooling the system as the venting doesn't trap any heat.

This is a small case at 11.5 liters which looks great. The lighting for power and drive activity is subtle and look good. No PCIe cable to deal with nor any issue with GPU sag since the GPU is vertical.

The only con is that you are limited to what GPU you use as the length of the case is

Nice case but does have a few flaws.

Why have air vents where the PSU will block?
Also the front grill, if you use a 120mm AIO cooler even configured as exhaust, a lot of the hot air ends up back in the case because it doesn't sit flush/close enough to the mesh and results in it just bouncing off and back in. This MAY not occur on the larger one (which makes you lose ability for full size GPU) because the top and right side gap would be less so no place for air to go but out.

Similar could happen on intake because it's easier to pull the air inside the case around the frame vs. through the mesh and because it's not sealed in any way this occurs.

I'd have like to see the case maybe an inch taller though. To allow for oversize GPU and also help with AIO coolers better. Right now I have an H80i GT and if I could go back I wouldn't do it because the space and the required force to make it bend. Making that extra inch adjustable would be cool too. In that case you could either give more clearance to the CPU cooler, OR keep it as positioned but fit a small fan on the top for exhaust.

I've got my PSU setup so fan is facing down sucking in and out the back to try to help exhaust more. This can make the PSU get warmer but it keeps the rest of the case cooler.

I've got an 6700k (these are thinner vs. prior chips and are known to bend and break under pressure if you google it so am worried about the cooler still) and it seems to idle in the low 30's and 60's under load or mid 70s under prime95 small test (worst one for heat). I only have the one fan on cooler and have a 980 TI FTW card. I've not yet done anything to warm the card up but I suspect that will increase the case temps since not a blower style card. The card temps will probably be decent given the side vent is right against the fans almost.

Overall nice case though. Hope some of this info can help some of you.

Also FWIW I had to exchange the case once. The first case had one tab broken on the front cover when I removed it. I figured I'd just build it and not put cover on and when replacement comes just swap the covers only. NOPE, found out one of the mounts for the MB is also bent. So had to wait for a case with all the fancy parts sitting. Was a little sad for a bit hah.

Before getting into the review, here is my build:
Intel Core i7-4770K Quad-Core Desktop Processor (3.5 GHz, 8 MB Cache, Intel HD graphics, BX80646I74770K)
Corsair Hydro Series H80i v2 Extreme Performance Liquid CPU Cooler, Black
MSI Mini-ITX DDR3 LGA 1150 USB 3.0 + SATA (6Gb/s) Motherboard (H81I)
Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory 1.5V
Samsung Electronics 840 Pro Series 2.5-Inch Solid State Drive, 256GB
Seagate 6TB BarraCuda Pro SATA 6Gb/s 256MB Cache 3.5-Inch Internal Hard Drive (ST6000DM004)
Gigabyte GeForce GTX 1060 Mini ITX OC 3GB GDDR5 Graphics Card (GV-N1060IXOC-3GD)
SilverStone Technology Platinum Certified Single +12V Rail ATX Power Supply, PS-ST55F-PT

I decided to take my old full tower build and fit as many parts as I could into a mini-ITX build. Clearly an ATX motherboard wouldn't fit in here. The MSI motherboard is fine, but I do have a minor annoyance with the layout. The front audio cable has to go all the way to other side of the case. I did have to get a new power supply because the old one (Corsair AX760) was too big. The PSU I got instead is adequate since it's 180 mm x 140 mm versus the standard 180 x 160 mm, but the cables are longer than I'd like them to be. An SFX form PSU would save a little more space, but you need to buy an extra mounting bracket for it. Low profile RAM would have saved even more space, but I wasn't about to buy more old DDR3 ram when mine still works fine. If I were feeling froggy, I would have taken off the heat spreaders.1

Installation was honestly a little frustrating but kinda fun at the same time. I had to put the build together and take it apart several times to figure out an optimal setup. Since I have a mini-ITX video card, I had space in the corner to cram excess cabling (looking at you, Silverstone PSU). I also had some space to put some of cables to the side of the video card as well (see 3rd picture).

Part of me wants to give this case 4 stars. There were tiny scratches on the front of the case, and I ended up creating more scratches while trying to install everything. That was partly my fault, though. Also, the right blue LED that shows up on the bottom front of the case came loose, so it doesn't look as bright as the left LED. That could have also been my fault when I was pulling out the front panel during installation.

I included a screenshot of my temperature range using RealTemp 3.70. Be sure to test your temps under load and also long afterwards to see if your build is properly getting rid of the heat. I actually had the fan in the wrong direction because I was going with the setup shown in the H80i v2 manual. It doesn't work the same way for this setup. You're trying to get rid of the hot air, not push it in. You are also limited to one 120mm fan. My PSU is also oriented with the fan facing down to blow cool air under load. You can't do that with air cooling solution that would have a fan typically blowing air up; therefore, I would recommend AIO liquid cooling.

If you're willing to be patient, I would highly recommend a mini-ITX build. When Ryzen and Vega come out later, I will probably keep this case and change out a few parts. For my purposes, there is no need for anything bigger. If it weren't for the AIO liquid cooler, I could probably get away with bringing it as a carry-on and traveling abroad.
