Video Editing and gaming PC for $1000

I was thinking about the following.. I don't know which video card to pick, nor do I know what case to choose. Do you guys have a favourite case? Something subtle, but with a window might be nice? Do these parts work together?

$1k Budget Rig

Just play with the graphics card a bit. I have a fairly big one in there that I should replace with the 660 ti, but if it is too over budget you can easily go with a lower card and still get good performance.

Edit: There we go now its a beast. If you can squeeze that extra $100 out, you would be set for a long time. The Agility 4 128GB also has a crazy rebate and is only $69.99. You could cut out about $50 by going with a cheaper case also.
