The Top, Bottom, and Rear Panels

The top panel of the 400R can be seen in Figure 7. It has a mesh, supporting the installation of two 120 mm or 140 mm fans.

The bottom panel has a big, removable air filter, covering the meshes available for the power supply fan and for an optional fan.

The rear panel and the interior of the 400R are painted black.

One of the highlights of the Corsair Carbide Series 400R is the presence of eight expansion slots. (Usually, cases have seven.) This allows you to install three or four video cards in your system, depending on your motherboard. The slot covers are vented.

There are four holes for hoses of liquid cooling solutions, all with rubber covers.

The 400R comes with a 120 mm fan installed on its rear panel, but no technical specifications for this fan are provided. This fan uses a three-pin power connector, so you must install it on your motherboard, allowing you to monitor its speed. You can replace this 120 mm with a 140 mm model, if you want.
