Oh and also.. If you decide to utilize all of the available space and free electricity, definitely invest in a SRR from simplemining.net. This thing is a fucking godsend man! I can't tell you how much time, gas, and money (both spent for gas and wasted while rigs were down) it saved me. If your not on location, and really even if you are, this thing is a no brainer!

BTW where in the office are you housing the rigs?
