I'm looking at buying a Mini-ITX board with some storage to serve as a Plex Server and Client. I'm wondering what the best OS to put on it is. Linux would be the preferred option but I've never used Plex on Linux yet, so not sure if there are any drawbacks (e.g. it looks like transcoding is flakey on Debian). Making it a hackintosh is another option, and there's plenty Mini-ITX boards that'll play nice with OS X with minimal fuss. However I'd like the flexibility of Linux (I may want to make the board serve as a NAS at some point too). Has anyone else done something similar? What OS did you pick?
