To be honest, if your main attraction is classic Amiga games and tinkering with the OS, you'd probably be better off with an old Amiga 1200 with a few recent expansions, accelerator, bit of ram, and a cf card full of games.
Agreed, keep it real
Or even WinUAE or an FPGA based solution (MiniMig etc).
Much cheaper than a new PPC machine if you just want to play Classic games.
