Cooler Master Cosmos II Case Review

The Disk Drive Bays

As already shown, the Cooler Master Cosmos II has three external 5.25” bays and two external 3.5” docking bays with hot-swap connectors and locks. Internally, the Cosmos II has three hard drive cages. The upper cage, located in the motherboard compartment, has five 3.5”/2.5” bays, while the other two cages, located in the power supply compartment, have three 3.5”/2.5” bays each. This allows you to have up to 13 3.5” devices or 11 2.5” de
vices with this case. All bays use tool-less mechanisms, except for 2.5” devices, which need to be fastened using regular screws.

The bottom hard drive cages have two 120 mm fans in front of them. These fans spin at 1,200 rpm and produce a 17 dBA noise level when set at their maximum speed. You can easily remove the door where these fans are attached if you so desire.

The bottom hard drive cages can be removed to give you space to install a 240 mm radiator for liquid cooling solutions.

Each 3.5”/2.5” bay is a small drawer. See Figure 25.
