Most of your choices are sensible, however I would change a couple of things
1) the case... it only has an 80mm fan for cooling - this would make your build run very warm. The best solution is for a case to have at least 1 x 120mm front fan, 1 x 120mm rear fan - this should be the minimum anyone would consider.
Antec 902 / 1200 would be perfect for your choice of components
Next up... 1000W PSU is all well and good, but a little over the top and could save yourself some money.
Finally - dont forget an optical CD/DVD drive
