I would also add: If you're planning on recycling your computer any time soon be VERY careful about the recycler you choose. According to NPR (and likely several other sources, NPR was just the first place I heard it.) the majority of computer recyclers in the U.S. are actually outsourcing their recycling duties to firms in developing countries, like China, where the computers are often not reused at all, but disassembled and scoured for precious metals. Parts that are not valuable for reselling are incinerated and these parts are often extremely bad for the environment when burned. Many people working for these recycling firms have gotten very sick.

If you plan on recycling your computer research the company and make sure that they will be distributing the computers for use by those that can't afford a computer or that they will be recycled properly with minimum environmental impact. Sometimes this might cost a little extra, but it's worth it!
