Lenovo, the artists formerly known as IBM's PC business, today announced a new "eco-friendly" PC, the ThinkCentre M57/M57p. This is the first desktop PC from any manufacturer to receive GREENGUARD certification as a low-emissions device, along with being EPEAT Gold rated, Energy Star 4.0 rated, and the first ThinkCentre made from recycled material from consumer plastics.

GREENGUARD certification means that the ThinkCentre M57/M57p was tested for up to 2,000 different chemical emissions. It is certified to emit very low quantities of chemicals like benzene and ozone indoors.

The M57/M57p features an ultra small form factor mini-tower case with either Celeron or Core 2 Duo processors, and come with Intel's vPro technology as well as the Trusted Platform Module (TPM) security chip, which uses hardware to encrypt keys, passwords and digital certificates. For added security, users can enable or disable USB ports through the BIOS.

The ThinkCentre M57 starts at $699. Monitors are sold separately.
