Main thing is the price is negotiable, I think 150 is to high since it is used no fan/heatsink or warranty. If you get it for 100-120 it is a good deal.
It's a good deal the CPU would cost 80 to 90 on ebay, the board is fine it will oc pretty good too, it will take 16 gigs of ddr3 @1666oc,, offer 120 for it and barter some, I'd probably go the whole 150 if i had to, but he said negotiable so negotiate
