Did you look into ckpool? The payout is different from other pools. You get 98% of the block reward if you solve it and nothing otherwise. I had a spare computer last year and mined with my cpu on ckpool just for fun. I looked at it like playing the lottery. I never won anything. Basically in your case you either get 14 cents a day guaranteed with slush pool or almost zero chance of getting about 6 btc with ckpool.

Is the Apollo noisy? Main reason I'm looking at getting it is I don't want to deal with the ruckus other Asics make.
