A Closer Look - Inside

Looking at the inside of the enclosure, the SL600M doesn't look too unique aside from the fact that Cooler Master uses nothing but its own tooling. But don't let the initial impression fool you as things are actually quite thought out—but more on that in a second. On the opposing side, you will find a large opening to gain access to the CPU cooler's underside, with rubber-grommet-equipped holes for cable management. On the bottom, where you would usually find a shroud in most modern cases, Cooler Master has placed two 200 mm fans set to push air up through the floor of the SL600M. Their aim is to create a chimney effect as hot air tends to rise, which is something we have also seen done by other brands, like Silverstone.


On the backside of the motherboard tray, you will find two trays for SSDs and several Velcro strips to keep things tidy. Last but not least, there is a PCB to control fan speed through the switch found in the front of the chassis.


In the front, a large metal plate ensures you won't see the somewhat busy elements placed here. On it, you may install two 2.5" drives to show them off to curious onlookers.


Behind the plate is a unique contraption that actually holds the PSU. It can easily be removed and comes in two parts. This allows you to install a longer unit while hiding it and, more importantly, its cables nicely.


In the rear, the bottom square with the expansion slots looks quite normal, as we have seen enclosures offer two vertical slots for perfect GPU showcasing. However, Cooler Master has gone a step further by allowing you to detach it and rotate it 90 degrees. This would technically allow you to showcase not one but two GPUs in such a configuration. However, to do so, you will need PCIe ribbon cables Cooler Master only sells separately.


Above that, where you would usually find a fan-placement possibility, Cooler Master has instead chosen to add another mounting plate for a hard drive, which brings the total up to seven storage devices that will fit inside the case out of the box. Thanks the numerous holes in the plate, you may also use it to mount reservoirs or pumps instead.


In the ceiling, you can clearly see the mounting holes that allow for up to three fans or a large radiator to be installed. Before moving on, note that the SL600M can be stripped pretty bare quite easily, allowing for easy and unobstructed assembly.


The cables within the chassis are all of the standard variety, with the only unique elements being the angled power plug to the PSU and the USB-C 3.1 Gen2 connector.
