TechReviewSource.com posted a review on the Lenovo IdeaCentre H520s
Lenovo continues to make strides in the slim desktop PC category with the IdeaCentre H520s. It combines a slim space-saving design with ease of use and a range of entertainment features. It features an Intel Core i5 CPU, 6GB of RAM, built-in wireless connectivity and a 1TB hard drive. The slim design does limit future expansion, but it comes with everything most users will need.Lenovo IdeaCentre H520s Review
The design of the IdeaCentre H520s is very minimal and slightly business-like although it's not specifically designed for businesses. The front face plate has a brushed metal finish while the sides are standard black. It measures 12.0 x 14.2 x 4.1-inches (hdw) and weighs 17.4-pounds, so it's much smaller than a traditional desktop PC design but still larger than some of the extremely compact desktops that Lenovo and other manufacturers make.
Lenovo includes a standard set of wired keyboard and mouse with the H520s. We found them to work well and comfortable to use considering they are only basic in design.
