The Lenovo ThinkCentre M57p eco is a green corporate PC that has a few more features than most small-business PCs. It comes in a compact black metal case and measures just 3.2 by 10.8 by 9.2 inches. A bracket mount is also available if you want to turn it into an all-in-one PC. It comes with a dual-layer DVD burner and internal 160GB hard drive that are full desktop size, making it easy to replace them. The M57p also comes integrated with Intel's vPro management integration platform. Because of its small size, expansion is out of the question. It has a generous amount of available ports including VGA, DVI ports, and 4 USB ports. What makes the M57p a green PC are the different certifications and even the amount of power used by the whole system. However, despite the small power usage, it achieved a great SYSmark 2007 Preview Overall score of 132 points, showing that it's ready to take on day-to-day office tasks. On the other hand, one of the major flaws of the M57p is the sheer amount of bloatware that goes with the system during purchase. Nonetheless, the Lenovo ThinkCentre M57p eco has the muscle for everyday tasks while saving your company money from the electric bill.
