A Closer Look - Outside

The MasterCase SL600M is one of the sleekest cases I have seen in a long time. Cooler Master has done an excellent job in regards to the design by walking the thin line of understated looks, but with gentile curves as well as angles to get past a simple rectangular box.


In the front, the SL600M features a brushed aluminium panel that rests on a plastic frame behind which you may expect the possibility to install fans or radiators. While the chassis body does suggest such an option, Cooler Master only advertises and intends for you to use the space for either two 2.5" or 3.5" hard drives. Looking at the rear, you will first notice that there is no PSU bay or fan grill, which is all in the name of containing the noise of internal components.


The main side of the MasterCase consists of a glass panel with black framing, while the other side is a solid steel one.


Taking a closer look at the front, you will find the shape of the Cooler Master logo laser-cut into an otherwise clean panel. In the very top are a true USB-C 3.1 Gen2, two USB 3.0, and two USB 2.0 plugs. Naturally, Cooler Master has also provided audio jacks. The interesting element here is the light sensor in the middle of the panel, which will light up the USB ports if any motion is detected.


At the very bottom, where you would usually find a PSU bay, is only a power plug. Above that are the 9+2 expansion slots which may be rotated to allow for two GPUS to be installed vertically. Nothing but the opening for the motherboard backplate has been put at the very top.


Across the top, a fairly elaborate cover made out of metal mesh and aluminium allows you to go for either sound encapsulation with some airflow or unrestricted access to air. With a bit of tough love, you may pull off the whole cover to reveal a plate that allows for radiators of up to 360 mm in size to be installed.


A gargantuan dust filter protects the whole underside from dirt and grime. Looking at it from below, you can clearly see that it is actually made up of two joint pieces, which means you could technically detach them and just use one or the other.
