This depend's mostly on where and how you sell the PS3 system. There are many factors that tie into how much money you will get back for it, like: is it in good working order, how old is it, is the warranty still valid, are you selling it online, on Craigslist, or on Ebay? So it's pretty hard to give you an exact answer to your question, but if I had to guess, I would say you would get back at least eighty dollars for the console only.
