Weren't the Alienware PCs of that era pretty effing loud?
If you haven't already, read Silverstone's FAQ on heatpipe orientation in the FT-02. You can find it in the Q&A section at the bottom of the product page.
There'a also a thread on it in the Overclockers UK
forum. Not trying to push you away from this case - just want to make sure you buy the right stuff for it.
$230 for the i7? did you mean $230 for the i5-3570K or $330 for the i7-3770K? In general, an i7 is a waste of money for a gaming rig as most games don't make use of hyperthreading and just use the physical cores.
You don't show any storage...SSD or HDD.
mobo: I think the whole "armoring" thing on the Sabertooth is just marketing drama. You'd do just as well with a Z77 V variant. Again, make sure the heatpipe orientation works for the case...and if you do plan to go SLI, look for a mobo with enough space between the PCIe slots for the 2x+ wide gfx cards to breathe.
gfx card: I like MSI. I think it's got the correct orientation for the FT-02 - make sure you double check. GTX 670 @ 1600p...is great for some games and not enough for others. Lots of benchmarks out there for the specific games you might want to play.
RAM: stay away from tall heatspreader ram - useless adder and just gets in the way of CPU fans. Unless you do photo or video editing, you don't need 16GB. Heck, most games are great with <4GB. 8GB is enough for today and any games you might play in the future on this platform.
PSU: If you don't plan to overclock or overvolt, your stressed load power with one GTX 670 is ~ 300W. With two, it's ~470W...and likely to be in the 400W range while gaming. I'd look for a PSU that's quieter than the video cards while gaming and it doesn't need to be a 860W PSU...however, you will need four PCIe graphics connectors. Seasonic Platinum 660W, Kingwin LZP 650, Be Quiet DPP 10 650W come to mind.
