Well you've certainly prepared for all eventualities but some reading your setup might consider it a bit of an overkill because you haven't got a clear idea in your mind as to what you want to do with all that hardware. You'd be surprised at how little you need to work with standard def video these days, for playing back on an ordinary tv (burning to dvd) or uploading to the likes of YouTube. High def video does require more resources, is this a route you intend to go down?
