Easy to do.... go to Masters, or Bunnings, they have little sheets of different panelling... buy the white coated masonite, cut it to fit, double side tape it (picture mounts) drill the access holes...apply and leave for 24 hours, no more gaps the cuts etc, then layout the power boards, drill and screw screws etc. Total cost $45 inc the power boards.
Oh and surge protector on the power point plug then extension cord to the board plugs behind the panel.
Still need to tidy up the right hand side cable wise, but waiting for the moon light and controller to arrive.
