Did you even read that thread crazyates posted?
Okay, results are just abysmal.
4.3 M/hash per second on average on the Intel HD 4000.
at 4.3MH/s you could make about $0.02 a day. If you walked up and down your local Walmart parking lot you would make more money picking up change... Its just not worth it.
On top of that when the reward drops by half you will be making $0.01 a day.... Plus the difficulty on the rise, I would guess in the matter of a month you would be down to less that 1 penny a day even with free electricity.
Even if you got 20MH/s it would only get you $0.04 a day.
