Personally, part of the reason I buy and sell old computers so I can experience more of them; there is absolutely no way for me to afford keeping everything I buy. I also love the experience of matching a buyer up with their nostalgia and meeting the buyers, who often used it when they were young, and talking to them hearing stories about it. On top of that, I'd rather it go to a good home than me make an extra hundred or two.

I also do have a bit of respect for pure flippers, because often they're the people who save it the first time. They might not care about the history of it, but hey at least they might be saving it from going to ewaste.
