Lenovo M57 Eco
Lenovo this afternoon pushed its line closer to complete eco-friendliness with the M57 Eco, its latest small form factor desktop. The tabletop ThinkCenter PC is not just energy efficient but also the first system to meet GREENGUARD's specs for a system free of chemical emissions. Even noise pollution is low at just 4 bels or less, Lenovo boasts. Some trim levels also rely on Intel's newer 45 nanometer Core 2 Duo processors to maintain this green status without compromising speed.
