I have a grudge against two things. That case and that video card...
If I were you, I would save myself $10 and get a Rosewill Challenger case. The case looks roomy, has a MoBo cutout, and looks like it has some pretty good cable management. Also, Rosewill is a part of Newegg so you really can't go wrong with them.
The video card... If I were you, I would spend $15 more (after rebate) and grab an EVGA GTX 560. They have a decent performance increase over the 6870. But, if you really wanted to hit the sweet spot in terms of the performance/dollar ratio then I would COMPLETELY recommend going with a gtx 560 ti. 2 of those in SLI (later down the road) blows any other single selling card on the market! They're GREAT. The lowest one out there right now is a Gigabyte gtx 560 ti and it's $210. Well worth the money to get one.
Oh and also... That motherboard scares me. Especially that company. AsRock tends to be extremely buggy with their products (I'm on one right now). I recommend getting an Asus or Gigabyte motherboard. Both are great top-of-the-line manufacturers. Their motherboards are definitely worth getting.
Hope this helps!
