Computer value money

[Cettycat]

Hey guys, I've been thinking about selling my old inspiron 531s computer for awhile now, and I don't know how much it'd be worth after using it for so long! it's in very good condition, it got put away for awhile so it's barely touched, and is now running windows 8.1. how much do you think I could get for this old computer?

Maybe $50 with the monitor.
