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.
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.
