I have the full set of blank panels by NANO and I have to say that the 2hp one have the holes not quite correct. More often than not the I cannot screw it in because the holes not quite match the rails. And the rails on my Amalgamod case are of a high quality and low tolerance. On the cases with sliding nuts this is not an issue (apart from sliding nuts themselves).
So we may say that the screw holes on this blank are screwed.
Other than that, it is a very nice panel.
All other blanks by NANO: 4, 6, 8hp do not have this problem.
