... The energy consumption is about 10 watt while a laptop consumes 90 Watt, in this way you save cost for the energy. Building a Node on Raspberry Pi is the same as a Bitseed and the costs may be the same.
My laptop consumes not more than 60 Watt even at peaks. So laptops, netbooks, those excellent little wonderful computers like the Raspberry Pi 3 Model B, or the Bitseed, choose which ever you may afford!
Just set it up sooner and run your full node!
