3 out of 5 eggsLooks gorgeous but is very inefficient with it's design

Pros: -Case is stunning
-Glass and aluminum design is very high quality

Cons: -No space for water cooling at all really. Will have to have a fan sticking out on the back of it. For the size of the case, that really sucks
-Cable management isn't very good

Other Thoughts: -Can't recommend this over the Phantek Evolv ITX.
-Mine happened to have an aluminum defect (just unlucky) and thus I had to return it.
-If they improve the interior design to allow for better space management and cable management, it would be much better. INWIN should take a look at the Phanteks Evolv ITX for their space efficiency.

5 out of 5 eggsVery nicely built.

Pros: This case is solid.
Nice aluminum and thick tinted glass.
A nice weight with well designed rubber feet alleviates any fears of tipping over if one wanted to place this tower on a desk.

Cons: None that I have found so far.

Other Thoughts: Would recommend as of now. I have yet to begin building my PC in it, though

5 out of 5 eggsGorgeous ITX case!

Pros: - High-quality tempered glass panels and aluminum body
- Fits large GPUs
- You can mount larger case fans than In Win specifies
- Excellent use of space
- Surprisingly effective airflow design

Cons: - Price is a little steep, but can be more reasonable with discounts. Considering the price of the 909, the 901 is still a steal.

Other Thoughts: The 901 is a beautiful, versatile ITX case with tons of surprises!

I'm was able to comfortably fit a Sapphire Fury Tri-X and OC a 6600K to 4.7ghz without temps getting out of hand under load in the small enclosure.

The specs list 92mm and 120mm fan mounts, but you can fit a 140mm to the rear radiator and another 140mm in the tray intake if you're willing to dremel a hair off the sides of the fan. This helps airflow and noise considerably. Note that mounting a 140mm to the radiator mount on the back can potentially make accessing the motherboard I/O panel difficult.

The glass panels can be reversed and screws loosely tightened to allow for 1-2mm openings around both edges of the case, allowing for air to vent a bit better and more room for wider GPUs and cables. The drawback is that it can allow dust to sneak in, but the 901 comes with a very nice black fabric cover that can be placed over the case when not in use. I like the look of the standoff-mounted panels, myself, and this is of course purely optional.

The tempered glass panels mute/dim any LEDs within the case in a lovely way and is overall a joy to look at from any angle.

The 901 is a deceptively capable case. Cooling, acoustics and aesthetics are all exceptional and speak to the quality of In Win's craftsmanship. Can't recommend it highly enough.

5 out of 5 eggsOverall Couldn't Be Happier

Pros: When I first saw this case it was love at first sight. I looked through almost all the cases Newegg had to offer and I kept coming back to this one. Throughout the build it has been a little bit of a love hate relationship because of the small form factor and some of the design choices used in the interior space, but after it was all said and done, I couldn’t be happier with the final result. There were definitely compromises I had to make from what I originally had in mind to complete the build, but in the end it was well worth it. The design and look is absolutely breathtaking in person. I watched a few reviews on Youtube and at times it was difficult to really understand their appreciation for the overall aesthetics and build quality. I can tell you first hand the brushed aluminum is gorgeous. It looks 100 times better in person. The case is extremely sturdy, well-constructed and impeccably engineered as a mostly functional work of art. A friend of mine that has been building computers for 5 plus years agrees he has never seen a case with such great build quality.

Cons: As much as I love the case there are some things I would change. The EZswap HDD bays may be convenient, but I don’t want to see those ugly black, yellow and red wires. I swapped mine out for all white Cablemod SATA connectors. The gap between the aluminum frame and the inner chassis is about an 1/8-1/4 inch which makes using the two holes for the USB 3.0, SATA, system power, etc and 24 PIN connector almost impossible to work with especially using more than 2 SATA connections. I think a case with this attention to detail and price range should consider individually braided cables for all that are included or at least cover all exposed wires. There are great braided cables that come with the case and are ruined by heat shrink tubing and exposed color wires. I would think people buying this case are going to put in the effort to make this build as slick as possible. My last complaint is that the interior, especially the HDD bay can very easily scratch. Nothing a little touch up paint can’t fix, but who wants to scratch such a nice case? And the two metal notches to pull the hard drives out rattle like crazy, so I just removed them, problem solved! Also, the back of the case could have really used a rethink on IN WIN’s part, but it can be removed so it is what it is.

Other Thoughts: This was my first mini-itx build (second ever computer build) and like another reviewer said if this is your first ever computer build it can definitely be a challenge. I would recommend that anyone building in this case to use a fully modular power supply and invest in individually braided cables for easier cable management. I chose to go with Cablemod. Expensive, but this is not a cheap case, and with glass on both sides this helps to keep things neat and tidy as well as keep the work of art intact. Also, depending on with holes you decide to run the cables through the individually braided cables are a must! I did make some PSU covers and added some IN WIN logos for a more customer look. I assume because most builds would take place in a mid-tower there is a lot of extra cable next to the power supply which look cluttered through the glass and this helps to keep the clean look as well. Spend a little extra money and make this case shine! It really is a great case if you are willing to put in the extra time and effort to make it work.
I am sold on the IN WIN design and build quality! I will be building a computer for my dad in an 805 after the New Year and I just saw the new 909 and I think that will be my next case. I will do the build I would have done for this case if I had the room. I also like the improvements they made in functionality for a bigger case over some of their others currently available.

5 out of 5 eggsBest Look Case!

Pros: Great looking case
Built is solid as a rock (Steel)
Looks great, performs great

Cons: No cons so far

Other Thoughts: I wanted something nice and sleek for my very first PC built, and i'll have to say this did the job (Prior experience is none - putting it together was a piece of cake). Had it for over a year now and I'll have to admit it still amazes me on how it looks.
My specs:
- In Win 901
- lntel i5-4690k
- ASUS H97I-PLUS LGA 1150 Intel H97
- ASUS GeForce GTX 970 STRIX (With modification to the tempered glass, but yes I made it happen)
- SAMSUNG 850 PRO 2.5 256 GB
- 2 x4GB G.Skill
- Noctua NH-L9i cooler
- 1x 90mm for the exhaust (planning to upgrade to a 120mm soon)
- 1x 120mm for radiator
- Rosewill HIVE Series HIVE-650 Continuous 650W

Future upgrades: water cooler

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.

Manufacturer Response:

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.
