9w idle: creating a low power home NAS / file server with 4 storage drives. Currently if you pay a somewhat average rate for electricity, the math works out pretty nicely: 1W = $1/year (approx) in electricity for something running 24/7. Subtract a little if you pay to heat your home, and add a little for extra AC in the summer.
