The Top, Bottom, and Rear Panels

The top panel of the Fractal Design Define R4 is meshed and supports the installation of two 140 mm fans. The mesh on the top panel comes closed with foam in order to reduce the amount of noise generated by the computer.

The rear panel and the interior of the Fractal Design Define R4 are painted black.

The case has seven expansion slots, using vented covers. A transversal slot is available for you to install a bracket containing I/O ports or a blower to pull hot air from inside the computer to the outside of it.

The rear panel comes with another 140 mm hydraulic-bearing fan (Fractal Design Silent Series R2, 1,000 rpm), which can also be connected to the available three-speed fan controller.

On the Fractal Design Define R4, the power supply goes on the bottom part of the case.
