I have a mac pro arriving tomorrow. It is coming with the 250gig drive with the OS and freebie apps installed (like ilife and such). I currently have these drives waiting: - 150g Raptor - 320g barracuda - 320g barracuda and of course, if I remove the 250, I'll have that too. 4 drives total. I am considering removing the existing 250 and putting the Raptor in as the boot drive, but my problem is that I've never worked with a Mac like this before, and I have never installed the OS on a mac. Will the Mac Pro come with all the CD's needed to reinstall it just like it arrived from the factory? Or will I be missing out on the ilife software that is pre installed? Also, does anyone foresee any issues with drivers or the OS install not recognizing something? I don't want to try and get fancy with the Mac Pro the first day I get it, and turn it into a doorstop by trying to replace the boot hard drive and reinstall the OS when I don't know what I am doing. But, this will be a VERY heavy use workstation for graphic design and web design, so I was thinking that the Raptor would be a great boost for the OS and application drive. Or am I crazy, and the Raptor should be used as a scratch disk, and maybe partitioned for some fast access storage as well?
