I'm all for people trying to build nonstandard computers independent of PC/Mac technology. Some of them may end up being pretty cool.
They won't be Amigas, though.
Exactly. Minimig is a good option for retro gaming. For Amiga desktop experience, go with common hardware. Amiga was a magnificent achievement back in the days when the chipset had to be multiple chips since the technology would not support a single chip. That was 25+ years ago, let's get with reality. If you want PPC, the only real option is either an old Mac or buy EFIKA. Or go x86/x86_64 route like ASUS EEE PC. I like to see the day when ARM based portables will be a real option.
It's about the OS, hardware is just hardware.
