If you’d like to save a little electricity, then there’s really only one option.  You’ll have to build your computer yourself, from the ground up.  Any collection of stuff stuck in a tower by a normal company won’t be the most energy efficient (or best) parts you can find.  That’s just how the system works.  If you want a good machine, it’s all on you.  Fortunately, Bit-Tech has a great energy-efficiency square off.

If you went with the most power-efficient parts on the list, then you’d shave off 104 watts of power usage without sacrificing any computing power!  The parts are more expensive than the standard bits, and you have to put it together yourself, but if you’re looking to shave off a little bit off your monthly electricity bill, then it might be worth the investment over the long-term life of your computer.

Sadly for an AMD fan like myself, Intel seems to rule the power-saving roost.
