In 1990 I did something similar with a Commodore 64. Mine wasn't as slick and well done as this one, but it had a C-64, two floppy drives, internal modem, RAM expansion, and three cartridge ports selectable via push button, in a case intended for an IBM clone. I was never able to find a good case for the keyboard, so I ended up putting it in a cardboard cookie box until I could find something better. After that experience, I got into the world of build-your-own IBM clones, and I don't remember what ever happened to the 64. Kinda sad.
