but back to hardware. So, you buy a couple of Radeon 5850's at $75 each, you buy a 1200W power supply for $150. You get some extra cooling hardware, say another $100. So your investment is $400 in hardware. We'll assume that your electricity is included in your rent. How long will it take you to earn $400 worth of bitcoins based on your chosen mining pattern? are you mining 24/7? 100hrs a week? let's say you are on a mining pool, you're generating say...i dunno..800Mhash. so you're earning around 0.4BTC per a day if you mine 24/7. (conservative). Let's say 0.5BTC a day. that's about $6/day. at that rate, it'll take you...67 days to recoup your $400 investment. Of course, many things can affect your mining performance, so let's be a little conservative and say 75 days. 2 and a half months. If you have to pay for power, then you have to factor those ongoing costs. Internet costs, etc.
