I have this old Dell Poweredge server and I want to use this server as a fileserver for our homenetwork. This will allow us to share all our music and videos over the network easier. Another reason why I want this to be my file server is because this will be used as source for my XBMC movie and tv show-library.
My question to you guys is: Which OS should I install on this server and why?
I was thinking of either Microsoft 2008 server, Microsoft 2012 server or Ubuntu server. Any other suggestions are more than welcome. I know ubuntu is free but I can get licenses for 2008 and 2012 server through my university.
