Debating buying a PC off marketplace to start Mining, help me

Title says it all. Late to the game but have some cash to throw around. Love RVN and even more so, the passive income idea. I don't know much about computer specs aside from my old laptop likely won't cut it. Can someone give me the basics using these specs as far as: – what would an average return on coins for x time frame – what I should look for (I know graphics cards are hard to.come by hence posting this PC here)

I know there is electricity cost too obviously. Thanks!
