Hi Sicky:
I am in the very same boat. For some time now, I have owned two Mac Mini's and decided to go the Mac Pro route as well. I too have to sell some of my Amiga gear. I am keeping one sole machine for classic games.
My stuff is still for sale.
here is the threadI hope I can get some takers on the equipment.
Anyhow, the Mac is the only platform IMHO that even remotely comes close to the Amiga!
It is hard to make the decision (I know because like I stated I am in the same boat as you).
But the positive side of this is that the Mac is truly a great platform and it is rock solid.
