COOLER MASTER NR200 ITX Mini Tower Cabinet (Black)

The Cooler Master MasterBox NR200 is a compact Mini-ITX small form factor (SFF) chassis that fits full-performance desktop hardware into an 18.25-litre enclosure measuring 376 × 185 × 292 mm (including protrusions). Despite its modest footprint, the NR200 accommodates demanding components without compromise, making it a strong choice for enthusiast SFF builds. Cooling flexibility is a standout feature of the NR200. The chassis supports up to seven fans in total, distributed across the top (2× 120 mm), rear (1× 92 mm), bottom (2× 120 mm), and side (2× 120/140 mm) positions. Two SickleFlow PWM fans are included out of the box — a 120 mm unit (650–1800 RPM) pre-installed at the top and a 92 mm unit (650–2300 RPM) at the rear. For liquid cooling, the side panel accommodates radiators up to 280 mm, and the bottom supports 120 mm and 240 mm radiators (recommended for custom loops). Rear radiator support is limited to 92 mm. The top panel does not support a radiator. Graphics card users will appreciate the generous GPU clearance: up to 330 mm in length (including power connector), 156 mm in height (including power connector), and 60 mm in width (triple slot). Vertical GPU mounting is supported via the rear PCI ventilation — a PCI-e riser cable is sold separately. Note that rear radiator installation and vertical GPU mounting are mutually exclusive. CPU cooler clearance reaches 155 mm in standard orientation, dropping to 76 mm when a GPU is mounted vertically. The chassis accepts Mini-ITX and Mini-DTX motherboards up to 244 × 226 mm, and supports SFX and SFX-L power supplies with a PSU clearance of 130 mm. Accessibility is thoughtful throughout. External panels and top-mounted fans are secured with tool-free pins, while the steel frame can be fully dismantled for deeper access. Dust filters are fitted on all four sides — top, bottom, left, and right — to help maintain airflow quality over time. Storage capacity covers 1× 3.5-inch bay (expandable to 2), 1× 2.5″/3.5″ combo bay, and 2× 2.5-inch bays (expandable to 3), with no 5.25-inch bays. The front I/O panel provides 2× USB 3.2 Gen 1 Type-A ports and a 3.5 mm headset jack (combined audio and microphone). The chassis is constructed from powder-coated SGCC steel, plastic, and mesh, and weighs 4.6 kg (10.1 lbs).
