MASTERBOX NR400 WITHOUT ODDFORM & FUNCTION STREAMLINEDMINIMALISTIC DESIGNThe 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 GLASSThe tempered glass side panel sits completely flush against the chassis, mounted securely and discreetly by a system of tabs and thumbscrews.
AMPLE STORAGE SUPPORTA 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).
HEADSET JACKThe single 4 pole headset jack features both Audio and Microphone capabilities simultaneously so that separate jacks are not needed.
