Soon after Dell updated their environment friendly PC line up with OptiPlex 755 (and rumored OptiPlex 330), Lenovo has unveiled A61e green PC in its ThinkCentre series. The ultra small form factor computer is Lenovo's smallest, quietest and most energy-efficient machine with energy-efficient, 45-watt AMD Athlon 64 X2 dual core / Sempron single core processor. Made up of 90% recyclable materials, the A61e boasts EPEAT Gold status and can be powered by an optional solar panel.

Other features includes 1GB RAM, 160GB hard drive, 64MB ATI Radeon X1200, DVD burner, integrated Gigabit Ethernet, and Vista. It'll be available from October with a starting price of $400.
