Help on case and cpu fan fit

[streetmike]

Hello, I am building a computer for my boss.

So far:

MOBO: Asus Px58d-e

CPU: i7 950

GPU: ATI firePro 4800

PSU: Corsair 650

Ram: G.SKILL Ripjaws Series 12GB

Case: Coolermaster elite 430 or Coolermaster 690(openbox)

CPU COOLER: XIGMATEK Dark Knight or CM 212


My question is will both cases fit the Dark Knight fine and will there be clearance issues with the ram?

We are leaning towards the CM430 because its NIB instead of open box.


Thank for the help.
