Should have gone with primecoins... I would guess on a pool you could get about 10 a day with that much power (assuming they were i5/i7 machines) and then traded them in for bitcoin. Although apparently the difficult of primecoin was raised a month or so ago. In any case going for another coin and trading is likely to be more profitable.
