green machines

I'm planning to purchase a desktop PC sometime this year. Fortunately,I came accross this Ars Technica article on DIY PCs with low power a consumptions. Honestly, I'm quite convinced. The coolest thing about the so-called "green PCs" is that they're quite affordable and in the long run, with it's low power consumption attributes, you get to spend less on electric bills. So, I guess I'll be "greening-up"
my soon-to-be PC this year.
