Looks good, Ray!
One thing you may want to think about-
With your woodworking skills, you could easily build the enclosure out of something like 1/2" baltic birch ply, then have it sprayed with line-x or similiar to weatherproof/toughen it! Cost vs. sheet steel should be fairly close, but you'd have better ability to trim it out the way you want. If you go that route plan on at least 1/8" clearance at moving parts, lids, etc.
