I haven't looked that close but for a computer its too old for anything other than retro gaming and it looks like it may be too cheap for that.
Edit: Now that I've bothered to 'enhance' its older than 2009. It doesn't look like a AM2 or AM3 socket to me. The processor has pins and the computer has a socket. Its a Pentium 4 socket 478 at best. With the plastic locking lever it may be socket 423 which dates it at around 2000. I would keep it just to fuck around with.
