use a small piece of 1/8 inch plexi. cut it to a 90 degree angle with arms about 1/2 inch long. on the back side of the mounting surface attach two brackets so the 90 degree piece sits in the middle and run a pivot through all three. make sure that the piece of the L is against the power button, and that the other leg of the L is flush with the mounting surface. now when you press on the exposed piece of the L, the other leg pushes the power button.
