Maybe Arduino is not the way to go: Give me your old PC

Willy is big enough that we could build a whole pc into it. Run Linux, and run whatever sensors we want to. It'll be a lot more powerful and won't have any of the size limitations the little processors did. Plus it could run it's own database. I'm gonna see if I can get a salvage pc from somewhere. Craigslist or something. Hook me up with your old PC if you're just gonna trash yours.
