MASTERBOX NR400 WITH ODDFORM & FUNCTION STREAMLINED Minimalistic Design Seamless Tempered Glass Ample Storage Support Versatile HDD Cage Headset Jack Fan Support Radiator Support Component Clearances STREAMLINED, BY DEFINITION Simplicity in aesthetics rarely reflect complexity in design. Cooler Master''s signature Fine Mesh spans the entire front panel for open airflow, makes up the structure of the case, and adds rigidity to its overall construction. Meticulously engineered for unhindered airflow, the MasterBox NR400 applies bold performance to a pure-and-simple design. 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 4 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.
