I would like to take a moment to share my unRAID server with the group, and how to accomplish building one for yourselves. Since WHS removed the drive extender option this is a NAS that acts in the same way. Just use it as a mapped drive on your network to hold your files.
The first link tells about the research put into the project and purchasing the equipment.
The second link shows a detailed approach to the build with how I dremelled the case, routed all the cables, and installed the software.
The third link shows a detailed approach to how I setup using Active Directory.
The fourth link will show using the server on a daily basis information.
I hope that this post helps users doing their research to be able to build there own server.
