I think it would be more of a PITA than it was worth.  A lot of modern 
hardware needs a fair old bit of setting up from software.

Maybe a "standard" motherboard to take an FPGA, fitted with a couple of 
serial ports, possibly USB ports, and an IDE controller would be a bit 
better?  It would be fairly easy to implement.
