It would help the bitcoin network, but not that much. With or without you, the whole thing would still operate the same way it was. One mining rig is nothing compared to the million/billion dollar worth of miners people already have. Why don't you help the bitcoin community instead?

You can always promote bitcoins to your local people and since not much people knows about it, you'd pretty much make a good percentage of your local people into bitcoin users. Especially nowadays when people are starting to get bored of doing Facebook and earn nothing. Bitcoins is staying online, doing some work, and you'll get paid accordingly.
