Mounting the Tuniq isn't easy either, You have to put a lot of down pressure on each thumbscrew at the same time as turning it for the screw to bite with the mounting plate underneath the board - hard on the fingers, and the its difficult to judge how far you need to screw in. I had a nightmare build last weekend, and suspect that it started with me screwing in too far and the screws touching the case and shorting the board

Off topic - any useful hints for mounting a Tuniq would be appreciatated.
