I really don't have an answer for why I haven't joined you all sooner. :shadedshu But, you can add 3 rigs to TPUs armada. My personal rig: E8500 @ 4ghz, on about about 30-50% of the time, idle for about a quarter of the time it is on. My wife's rig (once I get it put back together): E8600 @ 4+ghz, on about 3-4 hours a day, but almost never idle when on. My HTPC: E8500 @ stock speed (fucking Dell), on 24/7 and idle for about 90% of the time!!! The Dell will be the one primarily crunching for you guys since we never turn it off. With WCG now running me and my wife's personal machines I will be slightly less inclined to turn them off as often as I do now. I'll let them run a bit more. Bleh, what's a few more dollars on the electric bill.
