they have listed the item like that so that some poor sod looking for a bargain will be duped into paying a huge price for a box, and a fan that would be worth a few quid.
They didn't state "please not the box DOES NOT a PROCESOR", for example to make sure there were no mistaken bids. The seller was (no doubt in my mind) hoping for some unsuspecting person to pay over the odds.
He set the auction at 22:49 on the 12th, changed the description at 01:01 on the 13th, got his first bid at 07:03 on the 13th and closed at 22:49 on the 13th. The description was changed before the first person bid on the auction so no changes were made after the first bid.
