Check out the
68KMLA and
Applefritter. Those two and various other places are known to rescue aging Macs from the scrap heap. Also check out the
LEM Mailing List. You'd also be surprised to know that some people will even buy dead Macs in order to scavenge parts from them.
Incidentally, I have a Quadra 650 running as a webserver. I also have a Mac LCII, a Powerbook Duo 230, and an eMate at home as part of my collection.
