Cooler Master MasterBox NR200P Mini-ITX Mini-Tower Case (Black)

The Cooler Master MCB-NR200P-KGNN-S00 is a small tower chassis designed around the Mini-ITX and Mini-DTX standards, yet it still leaves room for full-size components. It gives builders who care about portability and desk space a way to run high-end hardware without the bulk of a traditional mid tower.

Inside, the layout accepts a graphics card that uses three slots and measures up to 12.99 inches in length. Air coolers up to 155 mm tall drop straight in, and a side bracket can hold a 280 mm radiator for liquid cooling. With mounting positions for seven fans spread across the top, bottom, front, rear, and side, it is easy to create an airflow pattern that keeps temperatures steady during marathon gaming sessions or demanding creative work.

Every outer panel detaches without tools, so you get full 360-degree access while routing cables, installing drives, or upgrading parts. The included PCIe riser card lets you position the GPU vertically, which can improve airflow or simply showcase a custom backplate and lighting.

Cooler Master ships two side panels in the box. Choose the tempered glass option when you want to display your build, or swap to the ventilated steel panel when lower temperatures take priority. Either way, the case retains a clean silhouette that fits naturally on a crowded desk, in a living room setup, or inside a travel bag for LAN events.

The top panel places two USB 3.2 Gen 1 Type-A ports and a combination audio jack within easy reach, so connecting peripherals or a headset never feels like an afterthought.
