The Cooler Master MasterBox 600 Mid-Tower Case Black (MB600-KGNN-S00) is a high-performance ATX mid-tower PC chassis engineered for premium gaming setups and intensive hardware builds. Designed with specialized support for modern back-connected motherboards, it provides compatibility with ITX, Micro-ATX, ATX, and E-ATX form factors. The chassis features comprehensive support for standard ATX power supplies and advanced thermal infrastructure, optimizing it for high-end airflow configurations and heavy cooling components.
A properly configured PC chassis is vital for keeping high-end computer components functioning optimally. The FineMesh performance front panel allows high-volume airflow across key system components to sustain structural performance and drop thermal loads under load. Its spacious internal volume offers extensive clearance for next-generation graphics cards, tall CPU tower coolers, and complex liquid cooling setups, while dedicated rear routing channels provide pristine cable management and clean airflow paths.
Motherboard Support: Compatible with ITX, Micro-ATX, ATX (including specialized back-connected motherboards), and E-ATX form factors up to 30.5cm x 27.7cm.
Cooling Support: Accommodates CPU tower air coolers up to 170mm tall, up to a 420mm front-mounted liquid cooling radiator, a 360mm top radiator, and mounting space for up to seven total cooling fans.
Power Supply Compatibility: Native mounting clearance for standard ATX power supplies up to 170mm in length, which expands up to 210mm when the internal storage drive cage is completely removed.
Included Features: Pre-installed with three bespoke 140mm SickleFlow ARGB front intake fans, one 120mm CF120 ARGB rear exhaust fan, an integrated hardware ARGB fan control hub, top and bottom fine dust filters, and 33mm to 35mm of dedicated rear cable-routing clearance.
In-Store Advice: Guidance on selecting the right case size, airflow design, PSU type, and cooling configuration for gaming, workstation, or compact builds.
Local Support & Advice: Assistance with component fitment, radiator placement, GPU clearance checks, and choosing compatible fans, AIOs, and accessories.
