Installation

The Cosmos S is a large case, made to fit E-ATX motherboards, using a standard ATX system gives you plenty of room to maneuver inside, the extra tool less features make installation a breeze and it will be over before you know it.

Most time will be spend with the hard drive bay which requires quite a bit of screws (4x per HDD, 4x for the bay).

The Cosmos S doesn’t come with a fancy goodies bag as the original Cosmos, which even had a custom screwdriver set:

No the Cosmos S has a rather standard looking content package, a detailed instruction manual, cable guiders and a bunch of screws:



Wait, there’s a cable there in that photo, an 8-pin extender cable, that will come in handy for hooking up your motherboard while keeping the cable hidden.

In the original Cosmos review we tried to route our cable like this:



But this prevented the side panel from closing properly. We are happy to report that the Cosmos S does allow you to route the 8-pin cable through the back as there is more room and better placed cut-outs and holes.

Another small change to the product design is the power supply area; the original PSU setup was like this:



If you install your PSU with its fan facing downward, allowing it to draw fresh air from outside the case, you might end up with one dusty PSU. Coolermaster must have thought the same:



Pictures say more than words; here’s the installed shot of the Cosmos vs Cosmos S

Cosmos S


You can notice cable routing improvements in several areas, the large 24-pin ATX cable is now hidden at the back and with the 24-pin pass-through on Cosmos S (for the touch sensitive power button) you don’t need a very long PSU cable to do it either. The 8-pin is now properly routed too. The 2x6-pin for VGA are also out of sight; The SATA cables make a return as the original Cosmos had their connection at the right side panel, here they are slightly more visible.
