Lenovo's ThinkCenter M57 is a very green corporate PC with a no-frills “old school” design. This compact computer has Intel’s latest 45-nanometer CPU architecture (code-named “Wolfdale”), yet the whole system consumes only about 58 watts of power at peak. It also has all the important green certifications: EPEAT Gold, RoHS and Energy Star 4.0. According to Lenovo, this machine also contains up 90% re-usable and recyclable materials and the packaging is 90% recyclable.

The system’s dual-layer DVD burner and internal 160GB hard drive are full desktop size, so they’re easy to replace with standard (and cheaper) parts in case something goes bad. Since the M57p is housed in a small-form-factor case, it has no internal expansion room to speak of, so you’ll have to plug an external USB hard drive or large-capacity USB thumb drives into one of the four available USB ports for more drive space. The system also is limited to integrated Intel GMA 3100 graphics. On the plus side, there are both VGA and DVI ports for either type of monitor, and the system does support dual monitors (one VGA and one DVI).
