Compact Mini-ITX Chassis

The Cooler Master MasterBox NR200 is a Mini-ITX desktop case finished in Arctic White. It accepts Mini-ITX motherboards and provides room for a single 120 mm fan. Builders who need Micro-ATX or ATX board support, or who want more than one 3.5-inch drive bay, should look elsewhere.

Thermals and Power

A single 120 mm fan can be mounted for airflow, and the chassis accommodates 240 mm or 280 mm radiators for liquid cooling. No fans are included, so acoustic profile and power draw depend entirely on the components the builder installs.

Included Accessories

Front-panel connectors provide USB and audio ports for external devices. The case ships without a power supply, tempered glass side panel, or RGB lighting, leaving those choices to the system integrator.

Questions about this item

How do I install a 240 mm or 280 mm radiator in the MasterBox NR200, and which step do builders often miss?

Mount the radiator to the side bracket using the supplied screws, then route the tubes before securing the bracket to the chassis; the step most often missed is checking tube clearance against the motherboard I/O shield and GPU back-plate before final tightening.

What maintenance will the single 120 mm fan mount and the 3.5-inch drive cage need over time?

Remove the magnetic dust filter on the side panel every few months and clean the 120 mm fan blades with compressed air; the tool-less 3.5-inch drive tray slides out for drive swaps without removing other components.

What thermal limit appears first when the NR200 runs a sustained load with a 280 mm radiator?

The side-panel intake feeds the radiator directly, so the first limit is the 280 mm radiator's ability to exhaust heat through the perforated steel panel once coolant temperature stabilises.
