I had one major row with my parents yesterday
Parents were complaining after we used 40kWh on the LAN. They asked whose systems used so much power. My 8 rigs of course. I told them my systems were 10 times more efficient than theirs (my average northwood system consumes ~60W), but the fact I was using 500-700W in my room got them a 'little' angry. They didn't believe me when I told them I was using that power only a few months ago with a single system and dual monitors.
All of my crunchers have been moved from my room, except the main rig and my lappy. They'll be back in a few weeks I think, but until that moment I'll only have a Celly 420 and P3 850Mobile running. Oh well, that problem should be over when I get my quad. I might get a QX6700 and dual 8800GTXs just to tease them
