The rear panel and the interior of the Cooler Master Cosmos II are painted black.

On the Cooler Master Cosmos II, the power supply is installed at the bottom of the case.

The case comes with a 140 mm fan installed on its rear panel, which spins at 1,200 rpm and produces a 19 dBA noise level when set at its maximum speed. This fan is connected to an individual three-speed fan controller, as previously discussed. The case allows you to replace this fan with sealed liquid cooling solutions with 120 mm or 140 mm radiators.

This case has 10 expansion slots with vented covers. An eleventh slot located perpendicular to the main expansion slots is also available and can be used for installing a blower (i.e., a fan for pulling hot air from inside the computer to the outside of it).

The Cooler Master Cosmos II has three holes using rubber covers for hoses of liquid cooling solutions. These holes are 1” (25 mm) in diameter.
