If I had only known that I was going to start Boincing again, I wouldn't have given all of my spare computer parts to the local recycle place! I literally had at least 4 old pc's worth of parts in the garage that would have made great, albeit slow crunching machines.
Funny how you need something shortly after you get rid of it.
I did this last year with my old minidv camcorder. I gave it to a friend who now lives 1000 miles away. Not a month ago, I found some old tapes from a Europe backpacking trip that "need" a camcorder in order to import it into my pc.
Maybe I'm not enough of a packrat...
