If you're in the Portland Oregon area, have some computer equipment to get rid of, and are inclined to do good in the world, you owe it to yourself and your neighbors to check out Free Geek, a non-profit organization in Portland that will take your computer donations and do great things:

Free Geek was founded in February 2000 (and incorporated as a 501(c)(3) in April 2000) to recycle computer technology and provide low and no-cost computing to individuals and not-for-profit and social change organizations in the community and throughout the world.

In the four years since its formation, Free Geek has recycled over 360 tons of electronic scrap and refurbished over 3,000 computer systems that are now in use by individuals and organizations in the community.

You can even drop by at Noon or 6pm, Tuesday through Saturday and take a tour.

Volunteer 24 hours at their facility and you can earn a refurbed computer with Linux on it. Donate computers of any type, in any condition - details here. They'll take old monitors, too - but there's a $10 charge, since they're like, nasty inside and all.
