I've been working with Final Cut Pro since v.1 and currently work as an Online Editor, so maybe I can offer you a helpful comment or two. First, there are the pro's for the Mac Pro:
- Internal drives. Restrict projects to specific drives and swap it out when you're done.
- Expandability. Can't add an AJA card to an iMac, for instance (although you can use the AJA IO, which is awesome). Can't add another firewire bus. Etc, etc.
- External broadcast monitors!
One deciding factor might be the type of content you're producing. Is it web-only? Is it for broadcast? If for the web only, the iMac might not be a bad choice. You'll never need to see your video on a broadcast monitor.
Or, if you're cutting for broadcast, but not working with colour-correcting/grading, the IMac could work, too. FW800 is fine for most formats. Most HD is compressed. There'd be no reason to use uncompressed if you're not finishing/onlining the show.
If you're finishing your material for broadcast, though, you absolutely need a way to monitor your work on a pro broadcast monitor. And you most likely need a way to get to a deck. You can't get HD-SDI out of an iMac.
One last comment about an iMac: you really can't lose if you want to start out on an iMac. It's an incredible machine and the best thing about it is you can easily sell it if/when you decide to move up to a Mac Pro. And you'll probably get most of your money back.
Hope any of that helps.
