ITreviewed posted a review on the Lenovo ThinkCentre M58p

The ThinkCentre M58p was designed specifically for the rigorous demands of large businesses and educational institutions. However, it's equally up to the task of running your small business. The design goal for the M58p was to be the greenest, most secure, most manageable and quietest ThinkCentre ever. Lenovo should be praised for its efforts, as with advanced technologies such as Power Manager and support for Hardware Password Manager, the M58p is one of the most complete business machines you can purchase. The ThinkCentre M58p comes with a limited, 3-year onsite warranty with next business day service.
