Interesting blog about experience with super-green PC Zonbu
First impressions - wow. Its hard to convey how small and light the thing is until you turn it over in your hands. With its silver heat sink and black accents it looks very modern and attractive.
It has a very minimal shipping box that mirrors the colors of the unit (so the large sides and grey and the small sides are black) and the egg-crate inside is made of recyclable material. There is not much surplus packing material, which is nice and eco-friendly.
