I haven't yet built my HTPC yet... but I installed Plex Media Server on my Synology - turns out my LG TV has a plex client. Boom. That was awesome. Unexpectedly, I was streaming my entire collection of movies to my TV... My blu ray rips were streaming perfectly. It looked amazing. Obviously my synology was not doing any transcoding... Got my wondering...
1) What's the min CPU required to have a snappy plex library w/ no transcoding?
2) What's the min CPU required to transcode a couple streams at a time?
I'm thinking about building my parents a cheap plex server + roku 3 box as a gift. I can build the server cheap if I don't ever tell them plex is capable of working on mobile devices ;-).
