2 out of 5 eggsBait and Switch

Pros: The Case is perfect for it's intended use (Micro-ATX), fit and finish is what I would expect from CORSAIR

Cons: The specs call for a two drive 2.5" expandable drive cage as does the manual.

My case was factory sealed and it did not contain the 2.5" drive cage.

Other Thoughts: This omission changed a good experience into one that left a foul taste for CORSAIR products. I expect to receive everything I pay for, nothing more, nothing less.

4 out of 5 eggsOverall Good but has a few issues

Pros: It is a overall well built little case. Good airflow and a sleek and high class look to it. Very easy to put the side panels on and off. This might seem trivial but coming from a Fractal Design Define R4 it was much needed improvement. Plenty of cable management as long as you do not use to many extension cables.

Cons: I had extreme difficulties mounting 2 140mm Aerocool Shark's in the front. It was a bit ridiculous. The motherboard panel was a bit flimsy same with the rear of the case. It came bent out of shape to the point where the rear I/O shield would not pop into place. I had to beat and bend it until it would stay in place. Also the number of SSD mounts it came with was 2 not 3 as shown in the picture. You can only mount 1 of them because they are spaced so close that the cables will not fit for the 2nd one. Also this case only comes with 2 5.25 inch drive mounts which really ticked me off. There is so much space and it is wasted.

Other Thoughts: The front dust filter is pretty much useless if you ask me. It isn't capable of filtering the finer dust particles out of the air only the bigger pieces. I attached some silverstone dust filters onto my 2 140mm front intake fans to try and solve this problem but I was forced to ditch this effort since they would not fit. The front space to mount fans is at most 26mm of clearance. Just enough for the fans and nothing else.

I would recommend this case if you are looking for a high quality microATX case. Much better than it's competitors (Bitfenix).

4 out of 5 eggsElegant and affordable

Pros: i just love the size and features of this case and the looks are striking yet subdued. I don't like edgy in your face cases nor boring looking cases. This is timeless looking case that was fairly easy to install an mATX dual card system. I installed an EVGA 680 (10.5" length) no issues as well as a Corsair H100i liquid cooler in the top. This was a tight fit and the direction I placed it had the hoses up front blocking the use of any optical drives (no biggie). I was also able to install the NZXT Hue RGB LED Case Lighting system which uses an 5.25 drive bay but had to install in the lower of the two bays.
Also upgraded all case fans and the radiator fans to Corsair Quiet Edition fans. Now I can't hear it until my ear is literally about 3 inches from a fan location.

Cons: The only real cons I can think of are that the front panels are that great looking brushed aluminum look and texture however they get dirty very easy and are hard to get and keep clean. Think of matte material and you'll get the idea. It's great to look at when its clean but boy do you have to be careful with it to keep it clean.
My other minor gripe is that when I put in a disc drive or the NZXT Hue lighting controller into the front they are recessed back and detracts from the clean lines that I loved about the case in the first place. This is worse with a disc drive (I have removed it as I don't use it and looks bad) it has a flat surface but it is just about 10 mm back from all of the rest of the front. With the lighting controller in however the knobs that would normally stick out are now flush so it is ok for me.

Other Thoughts: Over I am very happy with this case. During the build process there were a few things that made it a little difficult here and there but other than the tight fit of the H100i radiator they were small and forgettable once finish so not worth mentioning as most other cases this size are a sizable challenge in many regards.

5 out of 5 eggs

Pros: Plenty of room for cable management, lots of expansion room, great airflow, very classy design.

Cons: wish it had more drive cages

Other Thoughts: SSD cage can be removed and attached to top of HDD cage, this made running power to drives much easier and cleaner

1 out of 5 eggsPoor quality

Pros: Cheap, Good Cable Management

Cons: Matx, Nice window, Great Cabling management.

Other Thoughts: Poor quality,

Case came with scratches inside , Scratches on front bezel as well.

The front panel scratches were covered up with black Sharpie from the factory so I ordered a replacement,
The replacement had this problem as well
Contacted CorsairGeorge @ and he informed me that he will look into it and the qc process of Corsair,
Have not been rma'd a replacement without the scratches / sharpie cover up.

Will Not buy corsair products again because of this

Their qc and quality are going down hill really quick in the name of profit margin

5 out of 5 eggsBest MicroATX Case on the Market

Pros: - This case if perfect for a build with a microATX motherboard for someone who wants something a little more compact.
- Plenty of room for cable management behind the case.
- Window on side is massive and shows all the beauty inside.
- Comes with all black cables for things like front connector and front usb's. This is great because you don't have any ugly colored wires showing.
- comes with intake and PSU air filter so that your case doesn't get as much dust in it.
- The SSD and 3.5 bays can be removed.
- Can mount one 120 mm radiator on back and two 240 mm radiators on top and front for water cooling or closed looped setups such as the h100i.

Cons: - Flimsy panel on the window panel. I feel like I could break this thing in half with no trouble at all.
- Installing a radiator on the top can cause clearance issues with the 5.25" bay where you would put your CD reader/writer in.
- The window can scratch very easily so be careful when taking off and setting aside when working on your setup.
- Does not come with a fan controller. This can be a problem with anyone that plans on putting a lot of case fans into your system. Either make sure your motherboard enough plug-ins or invest in a fan controller.

Other Thoughts: This case is not really that much smaller than a Mid size tower. Actually I have worked in some Mid size towers that are actually smaller than this. So keep that in mind if you plan on buying this case.

4 out of 5 eggs

Pros: Tons of room for a MATX, capable of fitting a 240mm radiator both on the top and the front of the chassis.

Looks killer, and has built in filters on the intakes, which is great.

Very well built, feels solid without weighing a ton.

Cons: The 5.25" bay covers are wider than 5.25", by a considerable margin. When you install a 5.25 bay device, it doesn't sit flush with the 'front' of the case, but is recessed slightly into the panel. I ended up using the bay cover to make a 'stealth' dvd-rom install.

Other Thoughts: Was disappointed in how it looked with an optical drive installed, it totally broke up the lines of the case. However, it was easy enough to separate the metal faceplate cover from it's housing and attach it to the CD-tray door with two layers of 3M double sided tape. Now it's a stealth install and it looks great!

1 out of 5 eggspoor quality

Pros: Large

Cons: for $100 You would expect a obsidian case to be one of the best! but going from my amazing 250d to this..I was extremely disappointed in the flimsy doors and lack of fan filters! what the heck the 250D was so solid and i trusted this would be the same! very displeased by this case and probably will not even use it. you did great with the 250D why couldnt you have kept the same standards with this one? And these extremely cheap fans! really! they are of the lowest quality i have ever seen !

Other Thoughts: very disappointed in corsair

4 out of 5 eggsATX to Micro ATX

Pros: This case is manufactured very well. Allows for very easy install of hhd's and ssd's. It is a the perfect case for gaming!!

Cons: My only complaint is the pci slots, the screws are really close to the frame so if you have larger hands its harder put the pci screws in.

Other Thoughts: I shrank my system down from a Corsair 300R ATX case to this Micro 350D from Corsair for 2 reasons. One I decided that I didn't two have a huge case if I ever wanted to SLI or CrossFire and two the case is just much cooler then my old one!
