Mike Curtis of HDForIndies has written a very, very good article for DV Magazine detailing what you need to create your own uncompressed HD editing workstation. He splits it up by groups: barely-scrape-by budget, budget-sensitive, and fully professional. For each group there is a slightly different set of options to choose from, and he leaves it up to you to make the best decision for where you are at.
This is a great place to start if you want to create an HD editing workstation tailored to your needs.
