Please help with first time build

So heres what I plan on purchasing tonight when I get home from school. Everything here has pretty good reviews from newegg.com. I am on a tight budget, fairly close to what I have it at now. I will primarly use it for a media center/watching movies and video editing on a 50" 1080i toshiba DLP. the GPU was recomended because of this. I do very little gaming, and if i do its not the newest most demanding games. I am gonna purchase the case at a local store, its a little more, but no shipping charges. I have not decided on a blu-ray or just a dvd drive yet.
p.s. I have used some suggestions from here, and have been looking into this for a few weeks now
