The more I think of it, the thing that makes the most sense would be an adapter to fit the FPGA arcade or NatAmi into the classic Amiga case of your choice. ;-) Seriously, you're talking about duct taping a new built 68k/PPC card, graphics, SATA, networking, USB 2 board onto a 30 year old computer? When you're done you're only using the mouse & joysticks from the original Amiga....
