I am on your side and I own a LOT of classic machines, but what you describe reminds me a lot of UAE. It is FAST, uses current technology, runs the OS just fine, ect. It doesn't have the same "feel" as a real classic machine to me though and probably doesn't behave well with older games.
Just food for thought. I'm not trolling:-D I am watching the Minimig and Clone-A projects too. I just figured I would let the Minimig projects stabalize a little more before I figure out how to order up.
