With the advent of more powerful processors by the minute, cheaper RAM, and hard drives, many computers end up in the trash. If you are a grubby trash loving low-tech geek, this is a wonderful way to increase your supply of useless hardware.

If you live in a college town, I recommend checking the dumpsters behind the dorms as the students are leaving.

My best take so far: A fully functional 486 laptop, fully loaded (for 1992).
