Well, im still having great fun with my x86 PicoITX in a old A600 case,
It's now running a fast linux distro (CrunchBang Linux), and boots with E-UAE With Green Alien Edition, to give it a 'Real Retro Like Look' , it's also Running AmiKit, AmigaSYS 4, ScummVM, DosBox, Zsnes, Mupen64, some ZX Spectrum EMU, and CPCAmstrad emulation, but since the CPU is limited to 1ghz, it's quite slow for PSx emulation.
I'm also using it for feeding my ZX Spectrum, with fastloading games.
But The Real Deal is my Amigas,, nothing compares to it.
PS: i got some old pictures in my gallery about the thing.
