You have to look at the whole picture. What are your electricity costs? Then go look at a profitability calculator and plug in the numbers. Myself it is profitable, I picked up the same setup you are talking about, and I plan to use them to supplement the heat in my home, because I live in a cold winter climate. This helps cutdown my ROI time, as I would have spent that money on electricity anyways via my furnace.
Agree with this one. If you would look at everything and see how much you would really have to use as capital to mine, and at the end of the day, only earn for break-even or worse lower that what you've invested in. Some people say that it's not worth it these days, since the coins you would harvest is not as much as it was available before. Not to mention the capital like electricity, a good specs computer, and a paid third party program for mining; if you would only use one PC, I don't think it can go a long way.
