Unbranded 4U 19-Inch Rackmount Aluminum ATX Computer Server Chassis w/ Fan

Unbranded 4U 19-Inch Rackmount Aluminum ATX Computer Server Chassis w/ Fan

This is a 4U aluminum rackmount computer chassis designed to accept ATX motherboards and standard PC components in a 19-inch rack enclosure. The chassis is empty — no power supply, motherboard, or drives are installed — and ships as-is with the internal fan and wiring harness in place. It features a beige powder-coated aluminum and steel construction with black side carry handles and rack-mount ears on the front flanges.

Applications

This style of 4U rackmount ATX chassis was commonly used in industrial computing, embedded systems integration, and custom rack-mounted PC builds where standard ATX components needed to fit into a 19-inch equipment rack. The 4U height provides ample internal clearance for full-size ATX motherboards, multiple drive bays, and large add-in cards. These enclosures are used in data acquisition systems, machine control PCs, test-bench servers, and any application where a standard desktop computer needs to be rack-integrated. The front keyboard lock and separate PWR/HDD LED indicators are typical features of 1990s–early 2000s industrial and semi-ruggedized rackmount computer enclosures intended for shared or controlled-access environments. Rack builders, system integrators, and hobbyists still seek out these bare chassis for custom ATX builds where the rack form factor is required.
