Probably a silly question but is there an accepted limit as to how close a
built in microwave has to be from the wall. By that, I mean once it's slid
into the cabinet, does there need to be a certain amount of clearance at
the rear?

Usually 45 mm min. Don't know why but most manufacturers say something
around that.
