Or do the same thing that MGM does.

The controller board in the center and the two powerboards outside (with a heatsink)

How tall can be cube, like MGM?
I can put 2 PCB's with 12 FET's on each (both sides). With 4 FET's I hope we do not need heatsink, it would be heavy enough with all that copper from D2Pak tabs. Or we can add 3d board - 6 FET's - getting expensive ($5.00 each).

Or 2 FET's per phase and heatsink to frame? What if there is no metal frame? Electrical isolation can be done with regular heatpad.
