Exploring the Interior

The MasterBox 5's design and smartly placed tray cut-outs make light work of installing or expanding multiple interior configurations. Remove, slide and rearrange the internal layout to support larger, high-end components, air and DIY water cooling.

Expanding the Possibilities

For Motherboards

Motherboard tray cut-outs creatively rearrange space for any size motherboard.

For Storage

Tray cut-outs also allow for the easy mounting and rearranging of SSDs and HDDs across the motherboard tray, along the bottom shelf, or on the back side of the tray (for SSDs).

For CPU Coolers

No pushing! There’s enough elbow room inside, even for beastly coolers.

For Graphics Cards

Titans have a place inside too. Or your next VR-ready GeForce 1080.
