This is a very simple way of mounting a Pine64 board to the back of a monitor with VESA 100 mounting screws. It's just four little arms that you attach to the Pine64, then you attach this to the back of your monitor. It will print in under 10 minutes, and provided you have screws small enough (I think I made the screw holes on the Pine64 side a little too small), you can mount it in about 4 minutes.
