Minimalistic Design

The MasterBox NR400 is a pure and simple design that is focused on airflow performance. A single-layer, fine mesh makes up the entire front panel, achieving efficient airflow while also acting as a dust filter.

Seamless Tempered Glass

The tempered glass side panel sits completely flush against the chassis, mounted securely and discreetly by a system of tabs and thumbscrews.

Ample Storage Support

A total of 4 x 2.5" and 3 x 3.5" drives can be mounted using a tool-less system. Storage can be mounted on the PSU shroud, behind the motherboard tray, and within the versatile HDD cage.

*An extra 3.5" drive can be mounted only on the ODD version (pictured).



Versatile HDD Cage

The HDD cage is (re)movable. The cage can be shifted forward to make room for a longer PSU, backwards for additional radiator space, or completely removed if HDD storage is not needed.

Headset Jack

The single 4 pole headset jack features both Audio and Microphone capabilities simultaneously so that separate jacks are not needed.
