Cooler Master MasterBox NR400 with ODD

Form & Function Streamlined

A minimalistically-designed, compact case engineered for micro-ATX and mini ITX platforms. The meshed front panel pairs with a pre-installed front intake fan and rear outtake fan to create efficient airflow. A tempered glass side panel lets you admire and showcase your neat, clean build, which is achieved by cable routing space behind motherboard tray and a power supply shroud hiding cables and drives. Although with compact dimensions, the inside of the chassis is smartly arranged to accommodate high-performance components, while also offering flexibility to configure air or water cooling as needed. For easy access, two USB ports, a reset button, a Cooler Master logo-shaped power button, and a 4-pole headset jack are located on the top of the case.

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 4x 2.5" and 3x 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.
