For the cartridge doors, I sacrificed the case from a dead multipak and cut the entire door assembly out of it. It's held in the PC's front cover by some small screws and hot-melt glue (wonderful stuff).

The "sans CD-Rom" repack adapter includes my clone of the Tandy Hi-Res interface. I wanted it on the same circuit board as the other I/O connectors, for obvious reasons. There's a switch, barely visible between the two rightmost sockets, to choose between the left joystick socket and the Hi-Res socket.

My homemade keyboard... still not quite complete after several years. (I still need to make a top cover for it). Click for a closer view of the wiring. I forget what the keyboard came out of, but it's an old one with a good solid feel to it. It took me a little time to wire up but it was well worth it. It works great and I love it!
