Nah it was 98 or ME. That thing is pre XP. It looks like a socket 423. They were the only boards that had a plastic locking lever that I can remember.
Pretty sure it's a P4 on a 478. 423 is significantly larger and the cooler retenrion clip goes directly on the socket. This socket has no retention protrusions. Instead there's a plastic bracket that the cooler is attached to, but the plastic bracket itself has fallen off the board. You can see it on the cooler itself in the other photo. 😄
So 2001 to 2004 or 5 or so.
