Finally cut the slanted top/rear piece of the cabinet.  The big hold-up was the table saw my dad gave me; I couldn’t figure out how to get it to cut the 45’s I needed.

It turns out the handle to unlock the blade is reverse-threaded (and unlabeled), so it took me a while to figure it out.  (and by figure it out, I mean swear up a storm, throw things, and cracking the plastic handle).
