Attending a University and scouting for the least utilized PCs has left me w/quite a substantial stash w/out any extra cost, and after reviewing the hardware I've found that each PC is packing a quad core 3GHz processor. The GPU's are just Intel HD4600 so I doubt that will come in handy, unless I'm wrong and please correct me if I am. Now after doing some research I've come to understand that one of the best alt coins to mine w/a CPU is Monero, but I could be wrong. My problem is calculating the potential output of these PC's, and after looking over a few sites w/online calculators I find it hard to believe that each one can produce 100 coins in one hour so I must be doing something wrong w/the calculators. If anyone could give me a calculation, and perhaps even some pointers on superior coins to mine w/a CPU it would be greatly appreciated. Oh and yes the PC's are left on over night and yes I understand the risks.
