As others have said, AmigaOS 4.1 requires AmigaOne, SAM 440 or Pegasos 2. The upcoming AmigaOne X1000 will also run AmigaOS 4.x.
AmigaOS 4.0 (Classic Version) is available for Amiga 1200 equipped with BlizzardPPC expansion board. You would have to purchase a BlizzardPPC expansion board.
Current price for AmigaOS 4.0 (Classic Version): £71.51 from amigakit.co.uk
I do not have an A1200 so I don't have any experience with this version of AmigaOS.
AmigaOS 4.0 July 2007 Update ran very nicely on my MicroA1 which has an IBM 750 GX PPC processor.
I am currently running AmigaOS 4.1 Update 2.
My recommendations ...
1) A1200 ... I agree with Cammy. "I would leave the A1200s in their original cases and just get a 8MB RAM card or 030 accelerator and run a nice 3.1 system packed full of games and clasic applications"
2) AmigaOS 4.1 ... If you are interested in AmigaOS 4.1, you will have to purchase hardware.
SAM 440 Flex is available now. Advert says "Amiga X1000. Coming Summer 2010."
IMHO ... Stay away from used AmigaOne or used MicroA1 hardware unless you know the person selling it. These boards are no longer manufactured and are very expensive to repair.
BTW ... I am not against any of the other alternative "Amiga-like" systems. There are many choices, including emulation.
