Uh, maybe if that 0.0089BTC per GH (!) is for two years?...   in one year you should expect to net about $5 from it.

ed:  Oh, I see... it's 5 years.  OK, then it's about break even... you'd earn next to nothing in years 2-5, but it should be enough to cover the initial cost...

well, not really, because of inflation and better investment opportunities

not to mention the huge leap involved in assuming this place will be around for 5 years

ed2:  if it was more profitable to use it then to sell it to chumps, that's what they would do.  just sayin.
