This is a simple Underware mount for a Minisforum UM780 XTX.

It is not the prettiest, but should be hidden under your desk, so hopefully it is OK :)

It uses the mounting system from Underware 2.0 and I have included 4x Multiconnect connectors on the build plate, as that is what I used.

It should fit relatively easily, and can be secured with 2x M4 screws underneath: these screw into the mini PC directly, as there are mounting screw holes underneath.

It doesn't restrict air flow as there are holes in the side to allow intake / exhaust.

This can be printed without support: there are a couple of bridges that didn't print perfectly for me, but the print is still 100% functional. Perhaps if this was printed with PLA and not PETG the bridges would come out better.
