He spent about 30k total. He think hes gonna be a millionaire in a year. Not sure how big of a chunk the power is gonna cost him, but im sure its gonna be a lot.

He is going to lose money. If he mines at 20GHash with 9000W with bitcoins at $10 each (now they are at $7), he will cover the initial costs in 1 year and a half. However, the 7000 series will come out in the next couple of months and the difficulty will rise a lot. So unless bitcoin's price jumps to $30, he may never break even.

Hes probably losing money to electrical bills, so in theory he will never recoup his losses.
