Recycled PC: Old Computers with a New Purpose

Frequently, we find that new technological breakthroughs make old hardware that was just fine seem quaint. Be it a race toward higher clock speeds, faster front side buses, multiple cores, etc, computers become disused and replaced. Green attitudes have dissuaded people from tossing out components that are, for all intents and purposes, quite harmful to the environment. Moreover, current operating systems are becoming more power hungry let alone the software that runs on them. What's interesting about these computers is that in many cases they're perfectly usable.
