5 out of 5 eggsOne of the Best Case I Have Ever Owned

Pros: Sexy design. Love the large tempered glass windows.

Plenty of room for the largest graphics cards. My 980 ti fits perfectly.

There's even enough room for a water cooling system on my cpu.

Some people have spoken of the lack of airflow, but I haven't noticed it in my benchmark tests. I'm able to overclock my i5 all the way up to 4.3 ghz, and it barely breaks 50 C.

More than enough screws, zip ties, clamps, and cables included with the case. Also comes with a cloth for cleaning the glass, a nice touch in my opinion.

My 850 watt psu fit perfectly with plenty of clearance for good air flow.

Cons: It was difficult to plug everything into the motherboard with the radiator so close to the back of the motherboard. I have the radiator and fan in the small space in the back. Not worth dropping and egg seeing as you can just piggyback the radiator on the back of the case if needed.

Other Thoughts: If this is your first build, I wouldn't recommend this case as some experience is definitely needed in order to know how to route and orient all of the cables properly. I think it would be a challenge for people with no experience.

Other than that, it is a great case. Definitely recommend getting some leds and flashing ram to make it really stand out.

5 out of 5 eggsBeautiful mini-itx case

Pros: I have owned this case for close to 6 months now and I can say that it is probably the best looking case on the market for the mini-itx form factor. I use it as my HTPC and it is gorgeous in my living room. This thing was designed with a serious amount of thought, both for aesthetics and for builders. I build 3 to 4 computers a year and this is one of the most thoughtfully laid out cases I have personally built in. The hard drive cage is incredibly functional and well planned. Cable management is above average even in such a small enclosure. With both panels removed it is relatively easy to work in. Build quality is probably the best aftermarket non-custom case I have seen.

Cons: 1) While the inclusion of a slim ODD drive design is very handy (I have a blu-ray drive in as it my HTPC), it isn't the most convenient to use. I'm happy to sacrifice a little convenience for the stunning aesthetic though.

2) This case has room for a single 120 mm intake fan and one 92 mm exhaust fan. Buy both. Also, I would not recommend loading this case with an overclocked CPU and a power hungry GPU. The lack of good airflow will probably overheat your system.

3) I originally installed a closed loop liquid cooler on my CPU and mounted it it to the rear of the case per the instructions but the pass through for the cooling tubes is a little too tight. The cooler was also way to loud so I went to a low profile air cooler.

Other Thoughts: Get a modular power supply with low profile cables if you can. My PSU is 150 mm deep and I wouldn't recommend anything bigger than that due to clearance. You will also need a shorter CPU cooler, I used the Zalman CNPS8900 Quiet (it is a little annoying to install and you need low profile heat spreaders on the ram but this cooler works great).

This is a small form factor case so expect it to be. I did not knock any eggs off for the cons because the overall build quality and design of this case is truly awesome. InWin really produced a gem here.

4 out of 5 eggsIncredible Case with Little Limitations

Pros: The InWin 901 has a beautiful all aluminum exterior with very nice tinted side panel glass. Having an all aluminum exterior provides a very high quality feeling that most cases lack. Always a nice feeling in the morning to touch a cold case, reminds you of how great the quality is! Also don't threat on receiving a damaged case, it is enclosed with ample amount of packing and comes in its own sleeve to prevent scratches on the glass.

Cons: The InWin 901 does have its compromises. Like any mini ITX case water cooling isn't the first thing this case is made for, it does support 120mm Radiators on the exterior of the removable back plate and is fed into the case right above the 90mm rear fan slot. However larger AIO water coolers such as the Corsair H80i GT have a pump/block bigger than 90mm, and it doesn't help with having the stiff, wide, and sleeved tubes being mounted on the top of the water block/pump. Be prepared to bed some metal if you want to fir the H80i GT, also be aware that the side panel glass if fragile so it can break if the tubes are not tied away from the glass in someway. Also if you put a AIO cooler in the case be prepared to take the right side panel off as it will be impossible to remove the back plate to connect your IO.

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.
