Slight misalignment of mounting holes

[ChrisGammell]

During a livestream (https://www.youtube.com/watch?v=aSaus1-wG10) we found a misalignment of the holes on the elixir board and the expected footprint from the case vendor. Slight adjustments should make everything work a bit better. Currently there are no issues with fit, but only because of the "slop" we have in the size of the holes and the fasteners that we're using.
