X-Cube FAQ

Frequently Asked Questions of the MAINGEAR X-Cube

What advantages does the X-Cube chassis bring?

The X-Cube is one of our most affordable performance systems, all in the size of a shoebox. This is a chassis that can fit a Titan X and still fit snugly under your desk or by your monitor. With a large full panel window, you can deck out the interior with LEDs which, with its shape and size, gives you a system whose looks you won’t find anywhere else.

What type of systems work best with the X-Cube?

The X-Cube is one of our most affordable systems, but that doesn’t mean it cuts corners. The X-Cube is a bonafide gaming machine that would work well in any house-hold setting, either as a basic household computer, or a powerful gaming PC. With the ability to house both a Titan X and the latest x99 i7 processors, the X-Cube will always perform.

What colors does the X-Cube come in?

Right now the X-Cube comes in both Black and White chassis, each version comes with the full-panel window.
