The Supermicro CSE-502L-200B is a specialized 1U rackmount chassis engineered for high-density, space-constrained environments. Measuring just 9.8 inches (249mm) in depth, this chassis is specifically designed for deployment in shallow wall-mount cabinets, telco racks, and edge computing stations where a standard server footprint is not feasible. It supports a single Mini-ITX motherboard (6.7" x 6.7"), making it a preferred choice for building low-power network appliances, security firewalls, and dedicated gateways.
