Cooler Master MasterBox 600 ARGB White E-ATX Mid Tower Case

The Cooler Master MasterBox 600 ARGB White (model MB600-WGNN-S00) is an E-ATX mid tower case designed to accommodate a wide range of builds, from compact micro-ITX configurations up to full E-ATX motherboards measuring up to 12 x 10.9 inches (305 x 277 mm). The white steel and plastic exterior is complemented by a tempered glass side panel, offering a clean, contemporary aesthetic while keeping your components on display. One of the standout features of the MasterBox 600 is its support for back-connector motherboards, a design approach that moves cable connections to the rear of the motherboard tray. This frees up to 33–35 mm of cable routing space behind the tray, dramatically simplifying cable management and keeping the main chamber uncluttered. Cooling flexibility is a core strength of this chassis. The front panel accepts a radiator up to 420 mm, while the top supports radiators up to 360 mm — enabling high-performance all-in-one liquid cooling without compromise. Fan mounting positions accommodate up to seven 120 mm fans across front, top, and rear positions, or a combination of 140 mm fans at the front and top. Four ARGB fans come pre-installed out of the box: three 140 mm SickleFlow 140 ARGB PWM fans at the front (spinning between 650–1,800 RPM) and one 120 mm CF120 ARGB fan at the rear (650–1,200 RPM). An ARGB fan hub is included to simplify lighting control. The FineMesh front panel promotes unrestricted airflow, while top and bottom dust filters help maintain system cleanliness over time. A removable HDD cage improves internal access during assembly and upgrades, and also extends PSU clearance to 210 mm when removed. GPU clearance reaches 410 mm (without a front radiator), and CPU cooler height clearance is rated at 170 mm. The front I/O panel provides two USB 3.2 Gen1 Type-A ports, one USB 3.2 Gen2x2 Type-C port, and a 3.5 mm audio combo jack. Seven expansion slots accommodate multi-GPU or high-end GPU configurations, and storage options include two 3.5-inch HDD bays and up to six 2.5-inch SSD mounts.
