Replacing microwave, model no longer made

Got the new microwave installed and secured. I drilled 2 holes in the trim grill to match the holes on the old top trim. So that is real secure utilizing the existing "L" bracket coming down from the ceiling and secured to the facia. The four side screws now go thru the facia which is 3/4" particle board into 3/4" oak strips running the entire side. These side strips are screwed into the facia and into the walls. I pulled the power cord taught and nailed on a coax holder used to secure antenna coax to the wall. So this microwave isn't going anywhere. Oh, I shouldn't say that. It's going a great many places throughout the USA, but staying in the cabinet.
