ThinkCentre A61e. Fast forward a few months, and it's the same song and dance once more -- with even more green this time, though. The ThinkCentre M57 / M57p machines won't blow anyone away in terms of raw horsepower, but they are the first desktops from any PC maker to garner GREENGUARD certification. Additionally, these power-sipping rigs are EPEAT Gold rated, Energy Star 4.0 rated, and the first ThinkCentres with recycled material from consumer plastics. Internally, you'll get to choose from a range of Intel Celeron / Core 2 Duo CPU options, up to 2GB of DDR2 RAM, integrated graphics, an 80GB / 160GB hard drive and not much else. 'Course, with prices on the M57 starting at $699 and an understandable focus on energy-efficient components, we wouldn't expect much different.
