Power supply requires a mains cable to be connected to the HV side of the board. The opening is a bit big for most cables but can be filled to fit (SW files attached). M3 Screws all around to hold the case together. The screws were a bit tight on the top block due to my printer so I just plastic welded the connector to the top of the case.

The 4mm connectors go in from the bottom with a soldering iron tip, just like a press insert. Then I soldered a long, stripped wire to all the connectors of each rail, 5v, GND, and 12v.
This was the most time consuming part of the build. If plastic gets inside the connector, its okay and the clips will still work, however it can be removed with a drill bit. Push the plastic plug to the bottom of the connector housing and apply pressure with the drill bit while rotating it. This will cause the bit to bite into the plastic at which point it can be slowly rotated and pulled out.
