Definately make it a Windows Home Server. You don't know the peace of mind the ability to do bare metal restore gives you until you experience the need and can do it. Move to a new larger driver without the need to reactivate. Folder duplication gives you the ability to not loose important files no matter what. Headless server so no need for a monitor. You can also host a web site on said server....Current version is based on Windows Server 2003 and the next version (Code name Vail) is based on Windows Server 2008.
