Outdated Product
The open frame aluminum design is not the most common format among gaming cases, but this model from Cooler Master is aimed more at modding enthusiasts than standard builds. The FreeForm 2.0 concept involves access to files of modular panels that can be modified or replaced, adapting the chassis for specific tasks. The aluminum frame weighing 12 kg provides rigidity with completely open access to components, and the removable panels can be taken off without tools. In terms of component compatibility, the Cooler Master MasterFrame 600 sets an excellent standard: graphics cards up to 485 mm long, CPU coolers up to 190 mm high, motherboards up to E-ATX, and power supplies up to 235 mm. The cooling capabilities match the scale — four positions for water-cooling radiators each up to 420 mm..., and front and top bays accommodating fans up to 200 mm in diameter. Out of the box, it comes with three 140 mm Mobius fans and one 120 mm Mobius fan — a series known for focusing on airflow while maintaining moderate noise levels. Dust filters are positioned on four sides, although with an open frame design, their efficiency is inevitably lower than enclosed cases. The graphics card holder is included. The USB-C 3.2 gen2x2 port on the top panel offers a bandwidth of up to 20 Gbps.
