eBay remains the only reliable place to find good quality broken things, which is really important for reuse, repair of electronics.

It's also surprisingly good for niche items like a fan for a particular out of production CPU board.

A coworker once bought an old iMac to use to benchmark some satellite code because the old iMac and the RAD750 are pretty close (up to a factor 2 througout I guess). All eBay.

eBay is a national treasure.
