The rear panel and the interior of the Corsair Carbide 300R are painted black.

On the Corsair Carbide 300R, the power supply is installed at the bottom of the case.

The case comes with a 120 mm fan installed on its rear panel, with a standard three-pin fan power connector. Again, the manufacturer doesn’t publish technical specifications for this fan.

This case has seven expansion slots with vented covers. These covers are reusable.

There are three holes for hoses of liquid cooling solutions, measuring 0.8” (20 mm) in diameter. You need to break the metallic covers that come attached if you want to use them.
