APC NetShelter SX AR3103 12U Rack Enclosure 600mm x 1070mm | Server Rack

Keep critical equipment organized, protected, and easier to service in a compact floor-standing enclosure designed for smaller IT footprints. The APC NetShelter SX 12U provides 600 mm of rack width and 1,070 mm of depth, giving you the space needed for deeper network and server hardware without moving to a larger cabinet than the deployment requires. Side panels help contain the installation, while the enclosed format supports cleaner cable routing and a more controlled equipment environment. For teams building branch office racks, edge compute nodes, or dedicated network closets, this enclosure offers the structure needed to mount hardware securely and keep the rack area presentable for long-term operation. At 12U, it is sized for targeted deployments where density matters more than expansion. That makes it a strong fit for access-layer switching, compact storage, security appliances, and other equipment that benefits from a dedicated enclosure rather than an open-frame rack. When space is limited and reliability matters, this model gives you a disciplined foundation for the rack build.
