OMG, a whole 17watts!
You only read what you wanna read.
17W is the chipset. You still didn't answer which CPU you use. Those 45 or 60 Watts add to the total.
The system cost is always comprised of hardware price plus operating costs by usage period (unless parents pay the power bill).
@skynetsysadmin:
Do you even remember CRTs?
My education included repairing them. Why do you ask, is yours broken?
