Where do computers go when they die?

What do you all do with your hardware when it is too aged to be useful to you? For the last year, I have been collecting old hardware from people's donations and putting it to use. What I can't use, I will give away or recycle. Are there any others doing this? If not, please feel free to send anything electronic (especially computers) to me. For information, e-mail me at dbaldwin@caeinc.com. Most of the hardware gets made into useful things (Linux terminals, Linux routers) etc. and given away locally (here in Michigan) or non-useful things (clipboards, christmas ornaments, etc) and traded for useful stuff.
