You all crazy unless you under clock them for better effeciancy these miners might last years but you won't be making no money on them in less then 6 months !! The difficulty will be way to high so running them would be a waste of power !!!
Well that is not true for many of us. I have access to an office that can run 2 with 0 power costs. I have access to 3 homes that use electric heat I am attempting to create space heaters from these for next winter. I have been talking with one homeowner and set up one for her last month. I can use a 16 port switch and place many of them throughout her home next winter. She is tech savvy and has cable-vision for the net service.
I need to figure out best clocking for her 250 -325 should make these very reliable to run as a space heater.
