I have two athlon 64 that have been sitting in my stash of computer parts. They were sealed in plastic but I am unsure if they are in working order. I have a socket 754 mobo, but have since sold off the memory so I have no way to boot up the computer to see if it is still good. (I had installed windows on it last summer) The power supply is still good spec sheet here

Feel free to leave an offer on anything or everything.
