Hey everyone, I recently came into possession of a Mac Pro with the dual g5s in it. It currently has 512mb of ram but I will be upgrading that to 2gb at least. Possibly an upgrade of the video card as well to the ati 4350 hd. Anyways, I am looking to turn that baby into a Media Server/Hub for my home entertainment system. I was wondering what the best route to take software wise was with a powerpc processor, should I keep OSx? Should I switch and install something like ubuntu on it? Should I go with boxee? or xmbc? or plex? Just wondering what would work best on my system and what you guys would recommend for a "noob" in media servers.
