The internal mounting holes on the power board currently use a standard KiCad footprint for M3 mounting holes.
To account for tolerance issues between the mounting of the rear panel connectors and the manufacture of the enclosure, these holes should be changed to be a little oversized. That way the board is more tolerant of things not lining up perfectly.
Since the only critical position of this board is those rear panel connectors, and since they have their own mounting points, this is unlikely to have any real downsides.
