1U Server Chassis – Slim Rackmount Enclosures | Server Warehouse

1U server chassis are the slimmest rackmount enclosures available, occupying just 1.75 inches of rack space. They are ideal for high-density deployments where rack space is at a premium, such as data centres, colocation facilities and enterprise server rooms. Despite their slim profile, 1U chassis support standard ATX and SFP power supplies and offer drive bays for SSDs and slim optical drives. They are commonly used for web servers, DNS servers, caching appliances and network monitoring systems where processing power matters more than storage capacity. Our 1U chassis range is compatible with standard 19-inch server racks and includes options with rear-fan cooling and front-panel I/O access. All units are built for continuous operation in high-availability environments.
