Okay so here's the deal I'm currently running a pc I built in 07 to stream my media to my ps3 via ps3 media server on a kubuntu setup. I am looking to replace this with an iMac but i fall into the obvious problem that is, the imac has no room for more internal drives. So I guess my question is would a firewire 800 setup be enough to keep up with HD video streaming? My other thought was to get a mac pro. Any help would be appreciated. thanks!
