Cooler Master N400 - Mid Tower Computer Case with ATX Motherboard Support, Multiple 240mm Radiator Support, and Ventilated Front Panel

Real nice case to build with. Extremely easy to fit everything in there that I had (nothing fancy, biggest component was the GTX 570 and it fit no problem). Having the power supply at the bottom is real nice, it makes sense and it works perfectly. Plenty of room for proper cable management as well.The first one I was sent was damaged due to shipping (accordion-like box damage), stupid me I forgot to check the case before building and had the motherboard and everything in there mounted and then realized that yeah, the case had a big dent in it causing it to flex and so my video card wasn't able to fully seat down into its slot. It was at this point that I realized the case did have damage.So word of advice, make sure there's no dents in your case before starting your build. Amazon was great as always though with getting the replacement here fast.

Ah, there are a few inherent problems with this case. I really like that front is mesh, as it allows for a lot of airflow. Cooling should not be a problem with this case.However, cable management can be a problem. First of all, the PSU is mounted on the bottom, and the motherboard mounts near the top of the case. So you have thick power cables crossing the middle of the case. Maybe if the PSU is completely modular the cables might not be so bad but my PSU is only partially modular and the main 24 pin and the 12v cables are thick. There is very little clearance between the motherboard and the top of the case, and mounting a radiator or some case fans at the top is very difficult. If you use a large aftermarket CPU cooler, it'll probably be impossible. In my case, the ATX 12v and two fan headers are right at the top of the motherboard, which creates an absolute mess.Also, the filters at the top are somewhat useless, unless you're planning on using that for intake (I'm thinking that it's for exhaust, however).The tool-less SSD frame is somewhat flimsy, but usable. However if you plan to install fans on that door, you cannot use the frame.Other than that, the price is good, and the case itself is solid and it does look nice. I've always liked Coolermaster cases, and despite those few issues, this is a good case for the price. With careful planning the cable management issues can be mitigated, and using a closed loop watercooler may help with the space issues as well (I thought about installing one and mounting the radiator on the right side panel but making it an intake instead of an exhaust).

My previous case was a Thermaltake Armor series (extra wide full tower, all thick metal case). That was a solid case. This case by Cooler Master is much much smaller and lighter--the metal sides feel so thin that you might mistake it for plastic. Any hard pushing or accidents could dent or bend it.Pros: Has all mesh front and vents on all sides, very open inside, big quiet fans (2), optical, 3.5 and 2.5in bays have lots of room. Still has a floppy slot (if needed). You can route almost all cables behind motherboard by taking off side panel for a clean inside. MOST IMPORTANT: no bright LEDs or plexiglass windows. I guess I have grown out of that phase. It's black on black. Black painted insides. Throw a black motherboard and cards inside and it will just eat all the light. Supports lots of extra fans and water cooling radiators if that is your thing. My build uses no separate video card but it does support up to 12.6 inch video cards. Came packaged well, inside foam protects. Supports ATX and mATX motherboards.Cons: As stated before, the case is VERY light and just doesn't feel sturdy. I almost broke the 2.5in tray because it has a little plastic tab to remove it and it is thin.NOTE: You can't screw in the motherboard stand-offs by hand, there is a silver socket in the parts bag that you screw in with a screwdriver. First I have seen this.

Nice case. Toolless install is nice. Dedicated SSD slots is nice. Cable management is a bit wonky but that's more on me than the case manufacturer. Vented well, filters in place, quiet operation and easy access to ports. Front USB3 is great.

There appears to be a manufacturing defect. Both top fan mounting holes are too big for the standard size screws that ship with case fans. The right side and bottom fan mounting holes have the same problem. So I have a case that I can't mount the fans that I purchased. One Cooler Master support staff member went out and physically verified and acknowledged that the problem existed. That support staff member stated that the proper size screws were to sent to me. A week later I again contacted Cooler Master about the order status. The screws hadn't shipped and this time the problem was unique to my case. So here I am with an partially assembled computer and unable to use it. It will probably be a month from the time I ordered this case to completion.Cable management leaves a lot to be desired and the case ships with non PWM XtraFlow fans that you can't even find on their Website. My motherboard doesn't even have any three pin fan headers.

Poorly fabricated junk. Had issues with this from the beginning. The power button would not function. For the same amount of money you can get better cases. Stay away from this one.

This is actually one of the nicest cases I've ever had. Although it's a little misleading with the amount of fans it can carry, it's still can do quite a bit as far as 120 mm fans. It's really designed for a liquid cooled system, therefore the radiators are a little slimmer, and fit better. I was able to fit six fans in a very comfortably. If I had slim, or thin, fans would've fit a lot better on the top ports. The filters are great, and the wire management system is also fantastic.
