The Bottom and Rear Panels
The bottom panel has air filters for the power supply fan and for the optional fans.
The rear panel and the interior of the Cooler Master CM 690 II Advanced Black & White Edition are painted black.
The case has seven expansion slots, using solid covers. It has an additional expansion slot above the regular slots for you to install an I/O bracket containing connectors or a blower to pull hot air from inside the case.
There is a 120 mm fan on the rear panel (1,200 rpm, 17 dBA), using a standard three-pin fan power connector and also coming with an adapter in order to allow it to be installed on standard peripheral power connectors.
On the Cooler Master CM 690 II Advanced Black & White Edition, the power supply goes on the bottom part of the case.
There are two holes protected with rubber covers for hoses of liquid cooling solutions, each measuring 1” (25 mm) in diameter.
