Since its DV and not AVCHD, and you want to keep costs down, grab a refurb mac pro 2.8, got to OWC to put the ram up to a minimun 8 gb but might want to shoot for 16 gb, if your not comfortable doing a raid to start, get 3 1TB drives (1 for OS and apps, 1 for scratch disk, and 1 for your backup. If your going to raid, you will need more disks. Big question is what program are you comfortable using.. iMovie, FCE or FCP? I would not recommend using snow leopard now as have heard of hickups with the older versions of the 3 editing software not matching up well with snow leopard. Apple should be redoing them to take advantage of snow leopard and should be out early next year. Also a good monitor too.
