Ask HN: Do you have a lot of idle hardware?

Hey guys,

I'm trying to figure out if a lot of people have extra machines, either server grade stuff, or even desktop gaming rigs, lying around not being used. We've figured a way of building a cloud out of machines which can be parked anywhere, and I'm wondering if there actually is a reasonable amount of supply out there.

I know when I was working for a large Fortune 100 firm we often had piles of machines sitting in our datacenter not doing anything, but I'm not sure if that's common or not.
