That is crazy to hear about a $400 heating bill.
I haven't had a "heating bill" for about 3 years now - I have a year-round COOLING bill.
Or at least "ventilation" even in the winter, which sorta counts.
Yeah, I'll go with that counting. I'm hoping to avoid some of that come summer but we will see. Have you seen "Two Ton Hasher" on youtube?
He runs maybe 10-15 GPU rigs oh his screened in patio in central Florida.
