5 out of 5 eggsVery Sleek, Looks awesome!

Pros: Very clean, unique, looks better than a Mac, small, good amount of cabling management, roomy for a small mini-atx case. Touch sensitive "on" button is a great touch.

Cons: No 3.5" bay for optical drives. Only fits Mini-ATX motherboards!
Radiator needs to be installed outside of the case at the rear.
A bit difficult to connect all the usb cables and dvi cables because you have to unscrew the back panel to connect it and then screw it back. Not a hard thing to do, but it's a bit tricky when there's a radiator hooked on the back panel.

Other Thoughts: This case was really fun to build around in. The cabling management is thoughtfully planned out, there is enough space for a GTX 970 GPU, and the HDD bays are well laid out where and not very visible when the glass panels are on.

The screws are nicely sized so that you can just hand screw them without tools. Don't screw it too tight or you might crack the glass.

The only issues I have with this case is that it requires a slim optical drive. The drive bay is located at the bottom of the case where the bottom opening is. Internal slim optical drives are hard to find these days so I opted for an slim external drive with the same stainless steel finish to match the case.

Another thing that I don't like is that if you're going the water cool route, the radiator can only be installed outside of the case, this is a problem if you want to set up a push/pull fan set up on the radiator but it's not a big deal for me. It's very nice of them to design some holes to allow the water tubes to go through from the back to the inside so it's still maintains a clean look.

About the back panel though, in order to hook up all of your peripherals to the motherboard, you will need to unscrew the back panel to get access to it and then screw the panel back on. This is a bit tricky if you have a radiator attached to it and the water tube is a bit short. Kind of nerve racking since it makes you worry if the tube will come off the unit and liquid will start spilling out.

Overall, the heat dissipation inside the case is mediocre. There is one fan bay in the front, and you can install a 90mm fan inside the case at the back and a 120mm fan for the radiator.

Conclusion: Besides the set backs on those points, I will definitely build another unit with this case.

1 out of 5 eggsDon't Lose the Screws

Pros: Solid, nice looking cae

Cons: If you lose the screws & try to order replacements from InWin, you will not get an answer.

Likewise, I would expect that InWin will ignore any other potential inquiries if you ever have a problem with this case.

5 out of 5 eggsWonderful case

Pros: Very easy to get around inside to do cable management. The glass panels come off easily, the holes for routing your cables are easy to manage, and there are plenty of zip tie points. Once you're done with the cable management you can use the glass panes to display your wonderful piece of art!

Cons: Can be a little difficult to fit larger cable harness' under the main board.

Other Thoughts: If you want a beautiful solid case, this is your choice

5 out of 5 eggsAwesome lifestyle case.

Pros: Elegant design aesthetics,
Durable premium materials,
Compact form factor allows flexible placement,
Nice airflow and relatively easy to build in for size.

Cons: None

Other Thoughts: The reason why I dont think this case has any cons is because it is my first build and it is built better than any other case I have seen or owned. I wanted a case that was stylish and would last a long time. I really dont like all the plastic blinged out cases. I knew from researching this case what I was getting into so I wont mention things that I knew about before purchasing as a negative. As stated in a lot of reviews whether text or video - this case doesnt have the most options for cooling. You have enough room for a radiator on the back, but I am going with a low profile heatsink by Noctua. There is ample room on the backside of the motherboard tray to route wires nice. The magnetic dustscreen is a cool touch. The front controls area is tidy, the logo lights up, the glass is plenty eye catching in spite of how simplified the look is with the aluminum. Its a very modern look and a smaller foot print. The trade offs for those two aspects make the limited aspects of ITX much more bearable.

5 out of 5 eggsBest case ever owned.

Pros: Super beautiful. This thing is amazing. You can definitely tell its built with high quality parts...designed insanely well. The convenience of installing anything is amazing. I highly recommend this case. It is built tough for sure. Everything is solid...will last me forever honestly.

Cons: Absolutely none.

Other Thoughts: Wish it came with an LED strip :)

With a blue LED looks sexy.

5 out of 5 eggsSmall and Sexy

Pros: Very well constructed with great materials.
Gigabyte GA-Z97N-WIFI Mini ITX LGA1150
Intel Core i7-4790K
Corsair H55
Patriot Viper 3 Low Profile Red 16GB (2 x 8GB) DDR3-2133
Samsung 840 EVO 250GB SSD
Samsung 840 EVO 1TB SSD
SeaSonic 620W ATX12V / EPS12V
120mm fans x3

Cons: Not a cons but you have to know the space in which you're going to be working. Also, I found that my normal sized hands were a little large while fiddling inside the case once all the parts are in.
!! As has been mentioned, make sure your power supply is modular so that you have total control over bulky cables. !!

5 out of 5 eggsAwesome case

Pros: Super well made. Looks fantastic by itself and when fully built. Room for 5 drives including slim optical drive.

Cons: Not really and serious cons. Just make sure you buy the right components.
I got a tower style heat sink that wouldn't allow the side glass to close. Had to user a different style.

Other Thoughts: I wanted a powerful yet compact system with an itx case. I personally think anything larger than MATX is too bug unless you actually want 2+ video cards.
I put the following in mine.
Asus P8H77-I
Core i5 3350p
Cooler Master Vortex Plus
MSI 7970 Ghz edition
8GB of basic DDR3 1600Mhz
200GB SSD and 500GB HDD

Overall this system is pretty good.
Make sure to use the 120MM fan at the front and a 92MM at the back for proper airflow. I initially made the mistake of not using the 92MM fan in the back and the system got rather toasty. After, it runs like a dream.

I'm pretty impressed how well it all came out.

5 out of 5 eggsIn Win 901 Mini ITX

Pros: This case has the best fit and finish out of any I have had. It is heavy for what it is. Has a very thick "brushed" stainless steel look (although aluminum). It can accommodate somewhat long graphics cards, decent sized PSUs and even relatively large (not huge) air cooled heat sinks. Also supports water coolers. Air flow seems to work well for the most part if you use good fans (you have to buy your own). The tinted tempered glass gives it a nice look, although the glass panels are a little on the thin side. The screw accessory kit is very complete. It comes with screw bags that have an over-abundance of screws for most possible standard components that this case supports (and the bags are even well labelled). Also all of the drive bays have quick disconnect fittings which all line up real well with the components. Overall excellent quality!

Cons: So now the bad side of things. The slim dvd drive that the case accepts is in an awkward place (it is nicely hidden) but it is kind of awkward to pop the disks in and out of the tray from that position. Also it requires a floppy disk power connector for some reason, so if you get this case and really want to use this drive bay, make sure your PSU comes with a floppy power connector (or you need to purchase one separately). Also while it allows relatively long graphics boards, the width is another problem. I bought an MSI r9 280 and while the board itself fit fine, the power connectors on the side of the board were nearly flush with the glass. Needless to say with the power connections from the PSU attached, the glass couldn't be put on that side. Luckily since this case was for my daughter I put my older GTX 560 in which fit fine not only because it was more narrow but because the power connections were on the end of the board. (I kept the MSI board for my own computer replacing the 560) I was looking at the newer boards after this and most seem to have the connectors on the long side of the board. The only company that I have seen so far that seems to have kept them on the end is Club 3D based on pictures I saw. Also like many other ITX cases, cable management is a little bit more of a chore than normal. Also while not really a con, because of it being very substantial, it will weigh more than another mini ITX rig, so if you plan I transporting it, you may want to reconsider for that reason (and the fact that you may break the glass, scratch or mar your great looking new case!). Also the price is high, but in this case you get what you pay for.

Other Thoughts: As with any mini ITX case, I would recommend a modular PSU with good flexibility otherwise cable management will be more difficult. I decided on using a Noctua 9H-U9B SE2 air cooler on this. And while I would recommend a lateral air cooler like this (and the Noctua works very well) in this case because of where the intake and exhaust is, it looks like a big eyesore which kind of subtracts from the aesthetics of the whole thing. If I built the whole thing again I would probably end up putting a water cooler on it (and still might). Even with the cons I still give this 5 stars because of its great looks and excellent quality and wouldn't hesitate to buy it again.
