COOLER MASTER Masterbox MB520 Mesh ATX Mid Tower Cabinet (Black)

The Cooler Master MasterBox MB520 Mesh ATX Mid Tower Cabinet (Black) is a well-rounded mid-tower enclosure designed for builders who prioritise airflow, aesthetics, and build flexibility. Its FineMesh front panel draws large volumes of cool air directly into the chassis, keeping even thermally demanding components at safe operating temperatures without obstruction. Three pre-installed CF120 ARGB fans sit across the front of the case, each connected through the included ARGB/PWM hub. The hub lets you control lighting and fan speeds independently of your motherboard’s ARGB headers if needed. A fourth 120mm non-LED fan comes pre-installed at the rear exhaust position, so the case arrives ready to use straight from the box. The left side panel is tempered glass, secured by a tool-free pin system for quick, screwless removal. An optional screw is available for those who want additional security during transport. The removable top panel improves access to internal components during assembly and opens up the top mounting positions for fans or radiators. Cabling and storage are handled thoughtfully. Two combo 2.5″/3.5″ drive bays and three dedicated 2.5″ SSD trays offer flexible storage options, while the removable HDD cage frees up additional interior space when not required. Seven expansion slots accommodate multi-GPU or high-profile card configurations, and the front I/O panel includes one USB 3.2 Gen1 Type-A port, one USB 3.2 Gen2 Type-C port, and a 3.5mm combo audio/mic jack, along with a Reset/ARGB button. For custom liquid-cooling builds, the chassis supports up to 360mm radiators at both the front and the top, as well as a 120mm unit at the rear. Dust filtration is provided at the front, top, and bottom to reduce maintenance intervals. The bottom-mounted ATX PS2 power supply bay supports units up to 200mm in length (170mm recommended).
