The rear panel and the interior of the Cougar Challenger case are painted in black.

The case has seven expansion slots, using vented covers.

The rear panel comes with a 120 mm fan, which uses a standard three-pin fan power connector. No technical specifications for this fan are provided.

On the Cougar Challenger case, the power supply goes on the bottom part of the case.

There are three holes for hoses of liquid cooling solutions, which come closed with metallic lids. If you want to use these holes, you will need to break the lids and throw them away. However, the case comes with three rubber covers for these holes. These holes are 1.2” (30 mm) in diameter.
