5 out of 5 eggsA good case for an awesome price

Pros: There are a lot of things I learned about computers after building a first computer, and choosing a good case from a reputable company is one of them. Unfortunately, my first computer build did not use this case, but a cheaper model from a lesser known manufacturer. That was my first mistake and I regret it because I did not know what I was missing out on.
First off, if you intend to built a computer using an m-atx or itx form-factor, this will not disappoint. There are many upgrade options to choose from: four mounting points for 2.5" SSDs located throughout the interior, removable HHD cages on top and bottom, a spacious interior for large discrete graphics cards and good cable management, and the option to mount liquid cooling through the front of the case. Cooler Master crafted a mini-masterpiece using quality materials. Nothing felt cheap in this case. The filters are a nice fine metal mesh, instead of the cheap packing foam other manufacturers use for their cases. I encountered few sharp edges, had plenty of additional hardware, and everything on the front I/O panel works! The inclusion of two very quiet three-pin fans and a computer speaker made me extra happy.

Cons: I have very few complaints about this case, but I did find a couple of things that bothered me.
There is only one 3.5" drive bay, which I knew before I bought this case. It's no problem for me because I only needed one optical drive for a computer. But if you plan to include an external fan controller or flash card reader, you may be out of luck.
The only true gripe I have for this case is how troublesome it was to mount my SSD. I bought a Crucial M500 120GB drive, but found out that it could only be mounted upside down on the HDD cages. This proved a problem for me when I tried to connect the power cable to it. I eventually had to mount the drive to the motherboard tray to save me from using an extra cable from my modular PSU.

5 out of 5 eggsExcellent quality

Pros: well built with metal and plastic, there are two ssd docks, and two hdd docks, and its compact. supports one 3.0USB

Cons: my GPU didnt line up with the pci slots in the rear (sapphire r9 270x) and the space between the rear panel and the skeleton on the inside is only about 1-1/2 cm.

Other Thoughts: fantastic for a budget build without a doubt

3 out of 5 eggsNice Case

Pros: Nice quiet good looking small case. Has a front fan which I am not using.

Cons: Power button sticks. If I just barely press the button till it powers up it is ok. If I press the power button normally, it will stick.

5 out of 5 eggsGreat little cases

Pros: - Case contouring allows for some behind the MB plate cable routing (within reason)
- USB 2.0 and 3.0 ports on front of case
- Lightweight without being flimsy
- I don't have to listen to "Oh, I thought it would be smaller" when I deliver a machine
- Large quiet fans both front and rear
- External air filter under power supply mounting area
- No sharp edges, well machined

Cons: None, really. I wish they made an ATX size case in similar trim and features. Maybe add a second USB 3.0 port to the front? I'm pretty sure the cable already has the wiring, but then again, how many USB ports do you really want in the front?

Other Thoughts: Great little cases, reasonably priced and well made. Can't really find anything else in the price range of this quality that I would trust.

4 out of 5 eggsGood Value

Pros: Spacious interior, slots for HD, Disk Drive, and SSD. Slots and panels very easy to remove and reinstall. Cheap.

Cons: Little room between case for cable management

Other Thoughts: There isn't very much room behind the inner wall and the side of the case to stick cables, took some work to get the side cover back on with the power cables running through the outer layer.

3 out of 5 eggsCooler Master n200

Pros: Worked great for awhile.

Cons: Power button began to stick on, giving a bios corrupt error. Lucky I chose Gigabyte motherboard with dual bios.

Other Thoughts: If there is a cheap fix, I would like to hear it.

2 out of 5 eggs2 months and still no rebate

Pros: Great case, no issues with that, except having to mod an HDMI cable to fit with graphics card. Not a deal breaker and I knew this when I bought it. Rest of the case is amazing, space for everything uncluding 240mm radiator in a mATX case that fits in my entertainment center.

Cons: Dust shows up really well on the front of the case after just a week. Be prepared to remove and clean the bezel regularly.

It took cooler master a month to "receive" by rebate, and it's been another month and it's still "processing" I have since received rebates from Corsair and G.Skill from the same purchase date. Also, RMA'd a mobo to ASRock and receiced it back. This is a little ridiculous Cooler Master.

Manufacturer Response:


I am sorry that there has been such a delay in the rebate process for you. You can e-mail me at with your information, name, address etc. Then I can pass the info along to the person who deals with the rebate company that we use and get this situation taken care of for you.

5 out of 5 eggsN200 Perfection

Pros: I am quite satisfied with this latest project build. The N200 is perfect for utilizing small spaces. The black paint job is flawless inside and out. Superb ventilation and 3 more optional case fans can be installed - or a full size 240mm liquid cooling system and still have room to add 2 more fans on the top & side mounts. I built this project using an older mATX ASUS board and other older hardware that I have along with and AMD Phenom II 945 coupled with a Zalman CNPS 5X Performa CPU cooler with room to add in an extra fan on the side panel. The stock cooling is excellent btw. The included 120mm black fans are quiet, but since I added in 3 more Corsair AF120 LED fans, it has a nice "whoosh" sound effect - now I have 5 fans breathing inside this case. I used a new Corsair RM750 modular power supply and the cable management is great, since I took the time needed to route and position all the cables neatly behind the motherboard and tuck a few behind the extra space behind the power supply bay. I had to squish cables a bit while sliding the side panel back on but everything fit nice and snug. I was able to route the 4-pin CPU cable up and around the CPU cooler and up behind the additional top case fan's frame that I installed and it worked out great. I looked for and did not see a way Cooler Master could place another cutout for this cable at the top on the motherboard tray as others mentioned... maybe, but even then it would make it extremely difficult to position the PSU pins properly once the cable was put through the cutout, so I think this is why Cooler Master did not put the cutout at the top. Anyway, there is always a workaround for this need... it takes some time but WORTH it in every way to tuck everything neatly and compact-like. Sometimes, removal of some hardware I already had in place was necessary to happen in order to route some wires/cables as needed. The extra effort and time was WORTH it and adds even better cooling ventilation with less cables, etc. in the path of cooling airflow inside the case! The build quality is great and not flimsy at all in my opinion. Cooler Master put a lot of thought into this case. I really like the appearance on the front and filtration is throughout, including the bottom PSU vent. I like the front panel appearance even after removing the 5.25" slot cover to install the Blu-ray drive. True, it breaks up the front smooth look, but it still looks sleek. The side panel isn't filtered though, so I placed the fan there as an exhaust fan for the side panel so it won't pull dust inside the case. Also, I placed the top case fan as an exhaust fan, too.

There is a lot that can be done with this case as it is engineered to mount SSD hard drives, but I still used two 3.5 hard disks instead. I will use this as a little gaming PC and even as an HTPC---this case is great for HTPC's! The power switch and activity HDD LED's are a nice white glow and adds a nice touch if used in your entertainment system.

Cons: None. This case has just one bay for 5.25" optical drives, but do I really need two? No.

Other Thoughts: I also built a separate system with this case for a friend and they are pleased with it.... love it actually! Eventually I will be looking at the new Intel i7's Haswell Refresh 4.0 GHz costs/specs called "Devil's Canyon" (air- cooled and can be overclocked on air at 5Ghz CPU's coming out soon!!) and ASUS Intel mATX boards to put into this case, or perhaps AMD's newest if they can still compete with Intel...but for now.... I am using all of this in my build project:

Cooler Master N200
ASUS M4A88TD-M/USB3 mATX motherboard
AMD Phenom II x4 945 3.0 GHZ CPU
ASUS GTS450 1GB NVidia GeForce graphics card
Corsair 4 X 4GB Vengeance 1600 MHZ DDR3 memory
Zalman CNPS 5X Performa CPU cooler (with 4-pin PWM fan function)
Corsair AF120mm LED fans (three)
Corsair RM750W Modular PSU
Seagate 500GB 6gb/s HDD
Seagate 1TB 6gb/s HDD
Windows 7 Professional 64-bit
LG BH12LS35 12X Blu-ray Rewriter
ASUS VX279 HD 27" monitor
Logitech Illuminated keyboard
Razer Naga gaming mouse
Logitech z623 2.1 THX speakers

This system ROCKS! I have seen online that this case also comes in a Chocolate Brown color.... how unique is that? Looks great but different.

4 out of 5 eggsSmall defect

Pros: 240mm water cooler. Smaller size. Good air flow.

Cons: One side panel has an extra long lip and causes the panel to be more annoying than it should to take off and put back on. It's a small problem that doesn't effect the case overall but makes it look a little junky if noticed. It never should have made it past QC.

Other Thoughts: I bought this because I wanted to put a H105 on a kaveri and see what it could do. Very pleased with the case but -1 egg for the manufacturing flaw.
