Then I think you're good to go with this setup. Should be a nice rig; let us know how it turns out!
I don't know what case fans you were looking at, but all Rosewill fans are 25% off until 11:59PST tomorrow night at Newegg: EMCXRVT93
BTW, I looked at that MSI card you're talking about (I assumed you're looking at the 670 now with the price you quoted). It looks to have a nice cooling setup. Good choice. :9:
