I agree with a lot of whats just been said, I think some of this talk is over the top. Unless you've got a rabbit that lays golden eggs I would stick to a dual raid 10k rpm system at most and a quad core q9450 on an X48 with 4-8 GB of ram. Then get a very large drive for backup and be done with it. My setup is similar with out raid and I can encode full 1080p movies with x264, multiple passes in about 5 hours. This would normally take 3 days on a fast single core just a few years ago, so things have come a long way.
The problem with raid is that it's not perfect and it does fail and there are compatibility problems in some cases. I also would'nt have separate drives for input, output ect. This always causes problems for me in video editing and even audio conversions, it all depends on the bus. You mentioned audio editing, my brother uses pro tools, and he had one hell of a time setting it up since it was originally designed for a mac. I set him up with a fast system at the time with dual core multiple 10k hard drives, don't know if you're going to be using it, but just be aware that you might run into probs. no matter what you get, then you may even have to throw more money into it.
