Which rom revision does it have?
Nice that you've already got 40 pounds for that one with 9 days to go in the auction. Last month I tried to sell a A2091 with Rev 7.0 ROMs, the latest Western Digital chip and fully populated RAM sockets and I only got $35US for it after a ten day auction.
I'm not sure why as I've seen other crap ones (Rev 6.0 ROMs) go for over $50.
