Thanks Russ. Yep, finally got my second lab up and running. I've still got about 4 or 5 more of the 667's to get up, and then update the image on my main lab--that update should give me another 3-5k blocks/day as they are running findfast and openGL screensavers 24 hours/day.
Hopefully, I'll be able to keep the rate up for a while.
