CapRack is a modular 10-inch server rack mounting system that allows you to install more equipment in your mini rack in an aesthetic way.

A 1U in a mini rack is typically 222.25mm x 44.45mm. Many gears that people want to put in their mini rack, like mini PCs or SBCs , do not fit well in 1U. Often people would put such gears on a rack tray.

The idea of CapRack is just split 1U vertically into 2 CapRack modules, so each module can hold some gears and they are composable. Some examples:

• Put a mini PC module on one side, and a 2.5-inch disk mount module on the other side, you can make a mini NAS in 1U.
• Put a raspberry pi module on one side, and a small switch module on the other side, you get a proper network stack for your homelab.

CapRack is designed to be connected with M6 screws. As M6 screws are common in server rack mounting, they are easy to access to people who have a rack.

To connect 2 CapRack modules, you need 2 M6 screws (at least 12mm long) and 2 M6 hex nuts.
