Best home server OS?

I decided to build a small computer server to use Plex to play my movies. 

Which OS do you guys suggest to run it? I own a copy of Windows 8.  What are pros and cons? I was thinking about maybe Windows Server 2012, or FreeBSD??

I would like it to run using the least power possible at idle. 

Need hep. 


Hi well if it is only to play movies any os will do. If you need server capabilites like Mail server ,SQL data base server, 1000 system’s to connect to it then you need a server version of windows.  Now if you are going to use Plex Media Server you can not use any server version of windows as it will only support running on win 7, vista, win xp.
