I did exactly that back in the 90s (think 1995) with a 80486DX2. It doesn't take much parts to get a basic system running, but you need a lot of glue logic for RAM control and other stuff. I used a lot of 74F logic parts on those boards. The main problem was wiring all the components on a wire wrap pcb. Nowadays it should be much simpler with all the FPGA/CPLD stuff available.
