Just like the Deskpro 8086, the Compaq Deskpro 286 looks very much like a standard AT Desktop, but under the hood it's a proprietary machine. The 286 saw the removal of the front case LED light for Turbo status replacing it with a large, black, keylock on the front of the case. Also the case badging, at some point, changed from gold to Silver. Just like the 8086, it still used proprietary aluminum drive rails, a special single-ribbon power supply, 4x power ports on the motherboard for drive power using special cables, and had the Compaq DSM Monochrome Display power plug in the back of the machine.
