Phenom x4 consumes 110watt idle, whereas an Intel Nuc consumes <11watt idle. With usage of nine hours a day, 230 working days a year this amounts to 207kwh which in my country currently costs 108 euro's (power is expensive here yes). New (cheaper) Nuc set costs around 250 euro's. Fancier Nucs cost around 500 to 600 euro. Upgrading to more power efficient devices can earn quite some money back.
