Computer in a Suitcase

I've always been fascinated with technology of the past. Perhaps not the distant past, but definitely within the last half century. One such piece of nostalgia is the Altair 8800, what is probably the first personal computer. What I want to do is recreate that sort of device within a suitcase, it makes sense. I'm going to use the Z80 microprocessor, the same processor in the TI-83 and 84 calculators, and the Altair's switch based programming and 5 expansion ports to create this device. I'm already working on a schematic for the entire thing, but I doubt the board will be something I can etch in my backyard.
