Introduction

Cosmos S (internally called RC-1100 by Cooler Master) is a big full-tower case featuring aluminum body, ten 5 ¼” 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 on Figure 1.

On Figure 4 you can see the front panel from this case. As you can see, this case has ten 5 ¼” 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 ¼” devices you need to open the latches available on the sides of the front panel.
