Lately I've been driving around my neighborhood, looking through the tens of garage sales, finding computers that these people are selling for $40. I open it up, see it still has the processor and hard drive in it, and buy it. Turns out, a LOT of these have core 2 duo's in them, which sell for $80 on eBay EASILY, and after wiping the hard drive many times that sells for some extra.
It's amazing. Reminds me of the time my friend saw his neighbor put "free"on their computer which was left outside. He took it in, reinstalled Windows, and had a free computer. Gotta love people who don't know much.
