We're now 22nd!!!
Holy Crap - just got my electric bill, and it's only for 5 of my 17 machines (other 12 at another location, but I may have a coronary when I see THAT bill). Quick poll - how much is your electricity per KWH? It's 8 cents here in Charleston, SC, which seems a tad high. I vaguely recall Boston, MA being somewhere around 3 cents, but that was 8 years ago.
Correct me if I'm wrong:
5 machines at avg 300W = 1500W or 1.5KW x 24 hours x 30 days x $.08 = about $86 (total bill was $130)
so
12 at other location would be a little over $200? OUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!
