Sweet setup! I'm curious if you use the machines for anything when it isn't being used for a LAN party.

We'll turn on one or two to play games ourselves. E.g. my 5-year-old is currently playing Portal 2 at the station next to me.

But otherwise, no, not really. At least not so far.

Fun story: When I built the house in Palo Alto in 2011, people asked me if I was using the machines to mine Bitcoin. I said "What's Bitcoin?" I should have been mining Bitcoin.
