In the download center "https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Next+Unit+of+Computing+Boards&ProductProduct=Next+Unit+of+Computing+Board+D33217GKE" I am unable to find a listing of a Linux Operating system. Would the "OS Independent" be applicable to Linux?
If you Google "Intel Next Unit of Computing - NUC - YouTube" There are several good videos showing how to put this hummer together. The first listed by Carey Holzman I think is the best. He goes into great detail as to how to install the drivers.

Still waiting on the Haswell?
