With many thanks to @Mighty Man for supplying me 3 of these units in hope of a a capture of an original drive I am sadly still looking. I am hoping to find a copy of one of the 2.5" boot drive images or the PANAM.ISO recovery file for this server system. It is a Windows Server 2012 Essential system but can by upgraded in place to a modern supported windows server version. If you happen to have one of these wee beasties please do let me know and hopefully we can work something out. Ideally it would be a copy of the PANAM.iso recovery file for this model.
