How is an FPGA Amiga any more "real" than a UAE Amiga?
Actually is a nice idea if you wanna have a "real" (although hardware emulated) Amiga into a PC 
I made the opposite some years ago
- A1200 in DBox Tower case
- VIA Artigo Pico-ITX kit (5 1/4 case)
I had a PC inside my miggy that runned windows XP just fine
