Cooler Master MasterBox CM694

The MasterBox CM694 supports radiator mounting in multiple locations including the front and top of the case, accommodating common AIO sizes such as 240mm and 360mm configurations. Builders should check clearance between the radiator and motherboard components, especially tall RAM heatsinks, when planning a top mount.

The MasterBox CM694 includes drive bays for multiple 3.5-inch HDDs and 2.5-inch SSDs, with additional mounting points behind the motherboard tray for SSDs. The exact number of supported drives depends on whether you use the modular drive cages or remove them to make room for longer GPUs or front-mounted radiators.

The MasterBox CM694 is a mid-tower ATX case that supports standard ATX, Micro-ATX, and Mini-ITX motherboards. The case provides standard standoff positions for all three form factors, though Mini-ITX builds may leave significant unused space given the case's full ATX footprint.

The tempered glass side panel on the MasterBox CM694 is designed to be removable for easy component installation and cable management. Cooler Master typically uses a combination of thumbscrews and a hinged or sliding mechanism, though care should always be taken when handling tempered glass to avoid chipping edges.
