power hole updates
Holes J and K for the bolts to attach the microwave to the bottom of the cabinet over it are 10⅜" from the back wall. J (left side) is 11⅞" from the centerline; K (right side) is 13 7/16" from the centerline. Both of these holes should be ⅜" (technically the bolts you use are ¼", so depending on how good your tolerances are, you might be able to get away with a ¼" hole).
The power supply hole (M) is 5⅛" from the wall and 6⅛" from the centerline. It is 2" in diameter. In my experience, the wall distance was closer to 5½" and a 1 3/16" hole was more than sufficient (I had a hole saw in that size already and used it).
The roof vent opening (L) is 6½" on either side of the centerline and 4½" for a recessed cabinet (at least ¾" recess) or 5¾" for a flush cabinet.
