The Ramps board was just hot glued into place.
I designed and printed a replacement power socket holder, and screwed that into place.
The normal 12V input is run at 24V (D1 is removed), and the bed input is run at 12V from a BUK board. The BUK also supplies 12V to the Arduino via the power socket on the board.

I build a simple FET switch, running off the 24V supply, and connected the input to pin57 to run the case fan when the stepper motors are enabled. This means the machine is totally quiet when idling.

The hot end fan only runs when the nozzle is 30 degrees C or hotter.

I wired up a long IDC connector so that the cube's control cables would just plug in to this, and I soldered 4-pin connectors to the appropriate pins on the IDC. This is the hardest part, as it's not just pin1 to pin1, etc. However, it is easy enough to work out.
