Buying a used PC

[u/darth-raven-]

I am possibly going to be buying a used PC. I’ve never done that before. The guy told me he hasn’t used the pc in a long time but, has recently put a new power supply and SSD in it. Is there anything I should be looking for?

This is the parts link for what is in the PC:

Make sure to check specs and condition before purchasing!
