Cooler Master MasterBox NR400 Mini-Tower Case with window, Black

The Cooler Master MasterBox NR400 is a Mini Tower chassis designed for Micro-ATX and Mini-ITX motherboards. Its construction consists of a steel frame and plastic components, with a tempered glass side panel to display the internal hardware. The front panel is a fine mesh, designed to provide direct airflow to the system's interior for efficient cooling. This case presents a compact and functional layout for builders focusing on smaller form factor systems without compromising thermal performance.

Cooling capacity is a key aspect of the design, with versatile support for both air and liquid cooling setups. The chassis can accommodate radiators up to 280mm in the front, 240mm at the top, and 120mm in the rear. It comes with two pre-installed 120mm fans and has space for additional units. Component compatibility includes clearance for CPU coolers up to 166mm in height and power supplies up to 325mm in length.

For storage, the case provides a flexible configuration with an HDD/SSD combo cage, supporting up to three 3.5-inch drives and four 2.5-inch drives. The interior is arranged to facilitate clean builds, featuring integrated cable management options and a bottom-mounted PSU shroud. This placement isolates the power supply thermally and helps maintain an organized internal appearance. An integrated dust filter at the bottom simplifies system maintenance.
