I think I am stuck in a situation between an iMac and a mac pro. My iTunes library is becoming very large. Its getting to the 150GB neighborhood. I can easily multiply that 20 times if I wanted to rather quickly. (The DV collection and TV Show on DVD collection we have is huge) On top of that I have 20-25GB of music and a 30GB iPhoto library. So basically I need drive space. My Mac is an Aluminum iMac. I have the iTunes library sitting on an external 1TB RAID1 (500GB usable space) connected via FW800. Time Machine is using an external 320GB via FW400. Having those 2 drives connected just seems to slow my Mac down. Its a very noticeable improvement if I disconnect them. I rarely need the power of a Mac Pro. On occasion it would be nice to have. but almost 3k is a difficult amount to spend when I rarely need that kind of power. I could see it being used when I use iMovie or Handbrake, and I do use boot camp to use FS2004/FSX. I also do some light photo editing with Photoshop on occasion. The Mac Pro would give me 4 internal drive bays for storing all that media. That seems to be the biggest feature that draws me to it for now. Using the external drives just really suck. So the advice I am looking for is what can I do to make either the iMac perform better with the external drives I have (I may add more later), or what setup should I migrate to. Am I gonna regret spending that much on a Mac Pro? Maybe I can get an older G4 Power mac and use it as a "media server". What do you think?
