If you had a free power source and took it out of the equation, what would be potentially the best option for bitcoin mining?
You have limited space, so for about one or two computers tops. What hardware would you choose ultimately based on the basis it's available today?
e.g. Can top end graphics cards still be as good as a FPGA setup?
Can FPGA's out do ASIC in the aspect that the hardware is cheaper/ more accessible? or is it still not worth while in comparison?
