Hi, I am your man for your "green" computing needs! The D945GCLF is a great achievement in terms of power usage but it is actually much slower than what you would expect from a 1.6GHz processor. For instance the last version of it (D201GLY) with a 1.3GHz Celeron is still much quicker than the 1.6GHz Atom. Right now, the VIA C7 processor still has a better performance/watt ratio. And until Atom catches up with a more advanced version (Diamondville core), this is what you need http://www.jetway.com.tw/jw/ipcboard_view.asp?productid=283&proname=J7F4K1G A PCI Gb LAN card will use a few watts of electricity by the way, which defeats the purpose here. Keep an eye out for VIA's upcoming Isaiah core too - it REALLY is something amazing! Oh and by the way, for extra power saving, disconnect CD-ROM, mouse, keyboard, etc until you need to use them HTHs.
