Two, that motherboard is hugely unnecessary. 16X/16X CrossFire gives you a huge boost over 8x/8x at 2560x1600 of... wait for it... 1%. USB 3.0 is fine and all, but there's currently a very limited amount of devices that support it. You can add a PCI-E USB 3.0 expansion card to the Asus when it becomes more prevalent on devices later on. Three, 32GB SSD+500GB HDD>1TB HDD. The OP never mentioned having a huge media collection, so storage capacity is probably a non issue. HAF 912 is very good but it's pretty limited when it comes to its appeal. I know a lot of people that don't like the "military and rugged" look. I like it, others don't.
Four, rebates suck. I don't want OP to have to wait three months to see if MAYBE they send it. Mine is $698 instant.
1. Fixed, still under $699.
2. That motherboard is for AM3+ compatibility, your mobo will support a dead socket in a matter of months, and will be unable to have any Bulldozer CPUs on it - which is a GREAT loss and limitation.
3. 1TB is standard nowadays, if OP really doesn't need a 1TB drive, though the one I recommended comes at a great price and quality, he can go with your cheaper 500GB Caviar Blue.
4. He can go for the ASUS mobo, get the Caviar Blue and get the case you recommended to him and stay under $700. Problem solved if he wants to avoid rebates.
