Please trust me when I say that I really hate being the A-hole in the room, but just as I spelled out on Whyzzat.com, "I don't get it".
Without a solid, modern OS, hardware is irrelevant. It doesn't matter how fast it is, how much memory, or anything else... That is, unless the new hardware in question is/was never intended to be a serious device, but more of a tinker box for hobbyists with money to spend...
Really, I would welcome something different, but unless you've got a new, user-friendly and powerful OS (which AmigaOS used to be, about 33 years ago), what could you possibly use it for that a $30 Kano kit can't already do?
