Dell Studio Hybrid
Dell calls the Studio Hybrid its greenest consumer desktop, and both Energy Star and EPEAT give it the thumbs up. The Studio Hybrid's 87-percent-efficient power supply meets Energy Star's 4.0 green computing standards, and EPEAT gives the system its highest rating, gold.
The Studio Hybrid is 80 percent smaller than a typical desktop computer and uses about 70 percent less power than most standard desktop computers. The computer's packaging is made from 95-percent-recyclable materials and comes with less printed documentation -- 75 percent less by weight (all documentation is made available online instead) [source: Dell].
For an additional charge, you can personalize it with a bamboo sleeve. And when you're ready to upgrade, the Studio Hybrid comes with its own system recycling kit.
