Wouldn't think I'd ever catch myselv in advising against selling as a lot but since this is not a complete system splitting it makes more sence (even if it requiers more work). You lose the chance for top dollar on the items, especially the bigger the lot get's since you'll never reach a buyer who's looking for everything offered so they have to calculate with a potential loss and work selling some of the items further.
I'd at the very least look into repair/upgrade the PPC board becuase as a 040 board with defectinve PPC part it's not worth a great deal but pay 150-250Euro and all of a sudden you have a 7-900Euro (or more) part if sold seperatly... or possibly bundle it with the CVPPC and the SCSI adapters for an easier sale.
As it's listed right now I'd say around 750-800Euro, possibly a bit more if you find the right buyer but could also be less.
