a dual core athlon clocked at 3.1 is 3 or 4 years old, at least and it wasn't a top line chip then phenoms were. Its a Socket am2 or 2+ board. Its not really the start of a modern system unless you like the case. Its the sort of thing I would buy off of someone I know didn't abuse it and wasn't having issues with hardware to reinstall the OS and give to a kid cousin or grandma for emailing. The power supply will probably be ok.
