This is an APC NetShelter SX server rack enclosure, 24U in height with a 600mm width and 1070mm depth — a deep-format cabinet sized to comfortably house longer servers and networking gear with room for cable management and airflow behind the equipment. NetShelter SX is APC's established enterprise rack enclosure line, typically featuring a perforated front/rear door for airflow, side panels, and a load-rated frame suited to housing multiple servers, switches, PDUs and UPS units together in a data centre or comms room. This is a passive enclosure (the physical cabinet itself) rather than active equipment — power distribution, cooling and the servers themselves are separate purchases fitted into it.
