I'm buying a new Mac Mini... just for Plex (and running a BT client in the background). My choices are the 2.26GHz 2GB model or the 2.53GHz 4GB model... although I can equip the 2.26GHz with extra RAM if that's deemed helpful. HD size is irrelevant as I have a FW enclosure lined up for storage duties. Is 2.26GHz more than enough? What about 2GB of RAM? I don't want to run into any stuttering but I don't want to needlessly invest in overkill hardware either. Content is MKV's that are typically around 8-15GB. Thanks!
