Cooler Master N400 Closer Look: Working Components:
I removed both side panels and noticed the nice cut out in the motherboard tray that provides easy access for your CPU cooler installation. Two case fans are included with the N400: one at the rear and one up front. Both are 3-pin 120mm fans. The front fan has white LEDs.
The N400 gives you three nice options for liquid cooling. You can put a 120mm radiator at the rear, up top you can use a 120mm or a 240mm radiator, and now we have a side mount option for a 120mm or a 240mm radiator. If you don't go with liquid cooling, you can still put two 120mm fans on the side and increase your airflow. So for a fairly small case, you have some big cooling options. There are eight 3.5" drive bays, so space for your HDDs is no problem. Some cases have hard drive bays that can be removed or configured to allow for long video cards. The entire tower for all the standard drives in the N400 is fixed, so there is nothing to configure or move, but you do have 320mm (12.6") of space for a video card. The top two optical drive bays are tool-free, as are the top three 3.5" drive bays.
Looking at the back side, you will notice the integrated mounts for the side radiator or fans. It is tight, but you can get a radiator and fans in there.
When the front fascia is removed, you can see the 120mm included fan mounted in the middle. It has white LEDs. You can add a 120mm fan below that one if you like. This case can handle up to eight fans. Fan locations include: one rear, two on top, two in front, one on the left side, and finally two on the right side. The KKN1/KKN2 cases have a place for a single 120mm or 140mm side fan, and do not have a side window. The KWN1/KWN2 each have side windows, and of course no optional side fan.
For liquid cooling, Cooler Master recommends that the Seidon 240M be used for the top or right side and the Seidon 120XL or 120M be used at the rear. The upper tool-free slots are for the optical drives. At the bottom, the drive cage can handle eight 3.5" drives and there are also four holes on the case floor for a solid state drive (SSD).
There is also a small plastic cage for SSDs. It will hold two and the cage clips to one of the spots used for a side fan or radiator.
A view from the back side shows that the SSD cage can be mounted in a couple of different orientations.
The top can handle a 240mm radiator. Since the motherboard sits high in the case, the vent and fan mounts are offset to leave room for the radiator and fans. There is little space for cable routing behind the motherboard tray, so be prepared to have your cables showing. There is a top filter (not shown) installed from the factory and it is secured in position with four plastic tabs. On the rear at the upper left is the 120mm 3-pin rear exhaust fan (included).
The motherboard tray on the N400 is actually recessed a little, and this can present a bit of a problem for certain motherboards. Here is where I ran into one such little problem. The USB 3.0 socket on my MSI GD-65 motherboard is horizontal, and prevents the cable from being plugged in. Actually, I could plug it in, but it was really tight, and I don't like to put unnecessary stress on the motherboard or socket. I am not sure why, but the N200 and N600 have motherboard trays that are flush with the back plane, and did not have this problem. If your SATA cables plug in from the side of your motherboard, the recessed tray may make things a bit cramped, so keep this in mind.
The instrucions are easy to follow and understand. The hardware pack has the usual screws, system speaker, and zip ties.
Here we have the final assembly. While the options for cable routing are limited, there is room for everything, and if you invest a little more time, you could clean up the cables. A modular power supply would also help clean things up a bit. The Noctua D14 CPU cooler looks disproportionately large. Before you install a large cooler like this, double check that all your cables are plugged in and your RAM is seated properly.
