Looks good, no DVD/Blu Ray or any hard drives? Otherwise looks pretty solid. Haf-X is meant to have really good air flow. Either case would be pretty good.
PC Case Gear is great, good prices and shipping is good. I get my stuff from there.
the ripjaws might not fit under your noctua
also the noctua is an overkill for the 2500k, a corsair A70 will be fine.
I don't trust CM psus and so much money on a case i find a waste that could be used elsewhere. (like an ssd)
