You pay big premiums for a Caviar Black HDD. Drop that down to Caviar Green and get a 128GB Crucial M4 or 120GB Mushkin Deluxe Chronos SSD.
I highly recommend the Radeon 7950. It performs better than the GTX 580 and uses less power. Save yourself $60.
Drop down the PSU to 750W. Get the PC Power and Cooling Silencer MK 750W for $100. The GTX 570 is very power hungry.
Depending on the video editing, you may or may not need the i7-2600k. If the video editing is just a hobby, drop down to the i5-2400 and use the $ saved on a GTX 680. Otherwise, get the GTX 7950 and an i7-2600 (not the K version since you don't plan to OC).
You filled out "No" on SLI/Crossfire, yet you have a $175 850w psu up there and a $190 board meant for dual vid cards. That and you chose "No" on the over clocking part of the form yet you have a $100 hybrid water cooler. So what is it?
