This frame-less wall cabinet is melamine with a thin press-board backing, and it has no hanging rail. The press-board backing is set back from the rear of the cabinet about 5/8". The cabinet seems pretty heavy for it's size.
It was a shop project about 20 years ago and just takes up workbench or countertop space; not sure why anyone got an "A" on it without a way to mount it! I'm sure that if I just screw through the press-board to mount it, it will simply break and tear through the press-board, even if I fill the space behind the press-board.
It will be a stand alone, with no cabinet or wall next to it, so I can't screw through the sides.
I'm thinking that if I glue and screw a filler behind the press-board, it might hold, but it still won't be attached to the cabinet except for the thin backboard, and I just don't want to have to worry about it once it's hung and filled with misc. hardware.
Any great ideas would be welcome!

Install a "cleat" on the wall and hang the cabinet on the cleat. Screw through the thin backing into the cleat. The cleat would be thick enough to protrude slightly past the sides and top. One or two screws holding the cleat onto the wall would ideally be into a stud. Two other screws holding the cleat could be into drywall near the ends of the cleat to resist rotation.
