The Home Control Center
Media servers are designed to be an entertainment control center for cataloging, organizing and distributing the family's multimedia collection throughout the house. Using a wireless keyboard, regular Windows PCs are sometimes customized by vendors for this purpose, and they can also be built by tech-savvy users (see HTPC

When targeting the home theater market, Windows PC vendors build their machines in a horizontal case with the same dimensions as A/V components. See Windows Media Center
