@lectrick I have plans for a actual rig. At current prices, the system would cost me about $2200, but I would produce roughly $550 a month or 78 coins.Of course to convert them into cash, take out 5% for Mt Gox, then another 5% for their exchange partner. Basicly from selling to wire transfer you are going to lose between 10-15% in fees.

@lectrick Not really sure. Running off a 750w PSU right now. Currently I only have one (1) Nvidia 550 TI producing 30Mhash/s and one (1) ATI 5850 producing 280 Mhash/s. I have another 5850 showing up in a week. The 5850 use two (2) 75w 6-pin plugs so it cant pull more then 150w, plus I have them slightly under-volted so save on heat and power.

@elrodvoss How much are you spending on extra electricity a month?
