It supports ATX, Micro-ATX, and Mini-ITX motherboards and has dimensions of approximately 50 cm in height, 21 cm in width, and 45 cm in depth. It includes several dust filters at the front, top, and bottom to keep the internal components clean. The side panel made of tempered glass provides a clear view of the installed hardware while maintaining robustness. Storage options include two drive bays for 3.5-inch drives and four for 2.5-inch drives, allowing for various storage configurations. Cooling support includes up to seven 120mm fans or six 140mm fans, with radiator support for 360mm units at the front, 280mm at the top, and 120mm at the rear.
