Even then, paying the bill isn't as much an issue as having the wiring in place to support the power. At that level you need to have a subpanel or 2 installed.
I have a small factory that uses 1000 watt pressing irons. That low number (0.28!!!!) is from there, where I am currently paying about $2000 USD per month.
Now, I'm not sure the building is equipped to double the electric power consumption. Maybe I can run it only at night or something, when everything else is shut down.
I just need an excuse to tell the boss I'm setting up a new computer system. eh, hehehe.
Mark's place would be better.

I'll just own the hardware.
