Unlocked P4 on Ebay, No bids, 1.8 ghz ES Chip.

[TC]

ES = engineering sample. These are chips loaned out to hardware developers for testing and platform development purposes. They are never to be sold, and you must have special permission to obtain one of these chips. Selling it or transfering it to someone else is against NDA policy and can carry a stiff penalty.

Even though it an old Willemette?

There's PIII ES CPUs floating around too, does Intel really care about this older generation technology on an ES chip?
