Microsoft Windows Home Server, as its name suggests, is a version of Windows that you run at home as a server to store your music, pictures, videos and other media.
It also provides automated backup to help protect your individual computers.
Home server can run on a fairly low powered computer, and does not require a screen or keyboard as you can connect to it from your normal computer. The code is based on Windows Server 2003.
