Hi - I plan to convert an old tower into a media server, I'll need a new motherboard and processor and a few HDD. I have three main purposes: Storage of blu-ray and DVD for streaming to any of three displays in the home, for extenders there will probably be an Xbox at two of them With OTA tuner, creating a PVR solution Storage and source for my music collection Nothing out of the ordinary, but in thinking about what else I might want to do I want to be sure the system is powerful enough to transcode 1080p on the fly. No more than one simultaneous stream, I don't think. We all have mobile devices so I might as well. Can I get away with a quad-core i3, or should I bump it up to i5?
