That inevitable time in my computer "adventure" has come, I have a substantial number of retired CPU/mobos.

I have enough motherboards for each of these:

Athlon XP 2200+ - A
Celeron D 326 - LGA775
I still need any two of these, the other two would be retired:
Opteron 165 - 939
Athlon 64 X2 3800+ - 939
Athlon 64 X2 4000+ - AM2
Athlon 64 X2 4800+ - AM2

What to do with them? I don't think I'm going to go the selling route because none of these sell for enough for me to bother.. so ehhh..

I would try donating them to like a church or school. If not then recycle them.

I'll consider my old high school, but I'm not much of a donating person. The concept of losing something with nothing in return makes no business sense to me. I was wondering more like some cool specialized tasks I could put the computers to work for, like being a HTPC but what else?

Actually, Donating is normally free, where as recycle may cost to do. In all it beats a landfill.

Ah the recycling fee, stupid California charges that up front when you BUY the thing...
