I'm only currently running 4 machines too. I had planned on adding more, but that's not happening until winter.
I'm going to turn off the oldest machines (AMD Athlon XP 2000 and Core2 duo 6600) as they don't produce much.
Also turned off overclocking on my remaining 2 machines i7-2600k, i7-920.
I guess I wasn't expecting that much power usage, but I do run a portable AC to cool my pc's 24/7.
Kind of a downer really...
Better to focus on 1 or 2 good crunchers, that you can keep running.
I know I donīt produce as much as you guys...But my current production I can keep up for years!! Oh, and BTW...My powerbill comes every 3 months...Last quarter were around 900$..
