In Texas (dunno about elsewhere), Goodwill has "Computer Works" stores that take older equipment in working or mostly-working condition. They assemble systems from donated components and sell them for pretty good prices. Behind the scenes, I gather it's a training opportunity. What can't be fixed or cobbled together and sold, gets donated onward, recycled, or disposed. I take all my old systems there, and I check in the shop from time to time. I've picked up all kinds of stuff... full-size racks, HP servers, oddball adapter cards, vintage stuff.
