Cosmos S (internally called RC-1100 by Cooler Master) is a big full-tower case featuring aluminum body, ten 5.25” bays, a big 200-mm side fan and several other features. Let’s take an in-depth on this new case from Cooler Master.

This case comes inside a big bag, which surely protects it against scratches during transportation, as you can see in Figure 1.

In Figure 4, you can see the front panel from this case. As you can see, this case has ten 5.25” bays (three of them are used by the hard disk drive cage, so you have only six of them available; we will talk about this in details later). For removing the bay covers for installing 5.25” devices you need to open the latches available on the sides of the front panel.
