I wonder if there are low power Intel or AMD boards that accept DDR3. So many sticks of 2 / 4 / 8GB DDR3 inside laptops going into recycling or landfills which would do perfectly fine for low power purposes. Hell, performance for standard workloads scales with access times, not bandwidth, and DDR3 sits nicely at CAS8 1600MHz and CAS10 2133MHz..
