Overview
The Cooler Master MasterBox 520 Mesh ARGB (model MB520-WGNN-S00) is a white E-ATX mid-tower PC cabinet engineered for builders who want strong thermal performance paired with eye-catching RGB lighting. Its fine-mesh front panel promotes unrestricted airflow, helping keep temperatures in check even during demanding workloads or extended gaming sessions. Three Cooler Master CF120 ARGB fans come pre-installed at the front intake, and an included ARGB fans hub lets you manage lighting independently from your motherboard if needed. The tool-free tempered glass side panel is secured with pins for quick, screwless access, with an optional screw available for additional security. The removable top panel simplifies component installation and makes mounting cooling hardware significantly easier. For liquid-cooling enthusiasts, the case accommodates radiators up to 360mm at both the front and top positions (top radiators up to a recommended 55mm thickness), as well as a 120mm radiator at the rear. Total fan support spans up to seven 120mm positions across front, top, and rear locations, with 140mm options available at the front and top. Motherboard compatibility is broad, covering Mini-ITX, Micro-ATX, ATX, SSI CEB, and E-ATX form factors (up to 12" x 10.7"; note that larger boards may affect cable management routing). GPU clearance reaches 410mm, and CPU cooler clearance extends to 165mm, accommodating most high-end air coolers. ATX power supplies up to 200mm are supported, with up to 170mm recommended for optimal fitment. Storage options include two 3.5" drive bays and three 2.5" drive bays. The HDD cage is fully removable to aid assembly. Dust filtration covers the bottom, front, and top panels, with the bottom bracket locking securely during transport yet remaining easy to remove for cleaning. Front I/O includes one USB 3.2 Gen 1 Type-A port, one USB 3.2 Gen 2 Type-C port, a 3.5mm combined headset jack, and a combined reset/ARGB button.
