Cooler Master MasterFrame 600 E-ATX Mid Tower Case

The Cooler Master MasterFrame 600 is an open-frame mid-tower chassis built for enthusiast PC builders who demand maximum airflow, flexible configuration, and broad hardware compatibility. Its exposed exo-structure, designed around Cooler Master's FreeForm 2.0 philosophy, allows panels and internal components to be rearranged or replaced, giving builders a platform that can evolve alongside their hardware over time. Motherboard compatibility spans the full spectrum from Mini-ITX up to E-ATX and SSI-CEB, making the MasterFrame 600 suitable for everything from compact workstation builds to large HEDT and enthusiast gaming rigs. A maximum CPU cooler height of 190mm accommodates virtually every high-end air cooler on the market, while graphics card clearance extends to 485mm, leaving ample room for the longest dual- and triple-slot GPUs currently available. A bundled GPU support bracket is included to prevent sag during extended high-load operation. Thermal performance is a central design priority. The chassis accepts up to ten fans across the front (3×120mm, 3×140mm, 2×180mm, or 2×200mm), top (3×120mm, 2×140mm, 2×180mm, or 1×200mm), rear (1×120mm), and side (3×120mm or 3×140mm) positions. Radiator support is equally generous: up to 420mm radiators fit in both the front and top positions, a 120mm radiator fits at the rear, and 240mm to 420mm radiators are supported on the side. Four Cooler Master Mobius fans come pre-installed — three 140mm units in the front and one 120mm unit at the rear — providing immediate airflow without additional purchases. Dust filtration is provided at the top, front, bottom, and side panels. Storage options include up to two 3.5-inch HDDs and up to five 2.5-inch SSDs. Eight expansion slots accommodate multi-GPU or high-card-count configurations. Power supplies up to 235mm in length are supported. Front I/O includes USB 3.2 and a USB Type-C port for modern connectivity. The chassis is constructed from SGCC steel and aluminum and is finished in black. Cooler Master backs the MasterFrame 600 with a 2-year warranty.
