This isn't necessarily the lowest power machine - a newer chip will be more efficient, using less power for a particular speed. I've been doing a little research into low power computers for use as a basic home server, and many people recommend using a laptop, or a laptop processor for minimal power usage. For example most amd turion processors run at 25/35 Watts, while the same speed desktop processors run at 65 Watts or more.
Ensuring that you have your machine to run with a variable cpu frequency (I think this is fairly standard in modern distro) and setting it to powersave, or ondemand will help minimise power consumption, as will removing any non-essential hardware (sound cards, video cards - if you can use on board video) as well as turning off monitor(if you use one at all on a server) will help too.
