I would personally go with the Cooler Master CM690 II Advance as my case. 
 
Also, I would save a little and get a 5870 instead of the 480. 
 
Perfect choice for the PSU too.

Bump!
 
Anymore input from anyone, before I commit $1500.00+?

1440 x 900, but I was thinking about using my 1080p HDTV as a monitor as well through HDMI and I'm not sure it's resolution.

1080p is 1920x1080, strong cards are required at those resolutions. However, 1400x900 is teeny, so if you aren't going to use your HDTV seriously, don't bother with cards that powerful.

" @Rockdalf: You're missing an optical drive and Windows, assuming you don't have them already.  I would say drop the SSD and get a 1-1.5TB drive as backup instead. That's a nice find on the GTX 480 though, I haven't seen one that low on Newegg.  "

AMD processors and ATi video cards play nice together

I agree with Geno.  The SSD is pretty useless at this point.  They are still pricey for what they are and chances are you aren't going to be carrying your tower around very often. Plus you can bump your storage like crazy as well as drop the price if you get 1-1.5T.

I was going to use my HDTV for gaming, as they're right next to each other, but I don't know if I'll worry about it every time.  What kind of monitor would justify the 5870?  I'm already cutting back on a few things so I might be able to swing it. "

Another CM 960 II owner here, I'd definitely recommend it.  It's an excellent case, with some very nifty features.  The SATA dock on the top of the case is godsend for getting information off old hard drives without having to open the case up and install it.  
 
It is a smaller case than the HAF, though, so you may want to take that into account.
 
Also, I'd personally ditch the 480 in favor of the 5870.  Everything I've read about fermi seems to indicate that it's a furnace, and not worth whatever incremental gain you'd get over the 5870, and last I checked, the 5870 was cheaper.
 
Otherwise, that's a pretty solid build.

I've have two in crossfire, and they perform really well.  If you can stand to lose a few frames in crysis, I'm fairly confident one will do everything you need it to.

GTX 480 and HD 5870 are only overkill if you're playing console ports at high settings (admittedly, this is most games out there). If you're looking at stuff like Crysis and Stalker they barely perform at playable framerates. They're only just barely enough for 60fps in more demanding games like BFBC2. Neither of them even hit 60 avg in Just Cause 2. Factor in 3D or multiple monitors, or a higher res (using either a 2560x1600 monitor or supersampling) and the frames drop even more (several times over in fact). Don't get me wrong, they're still top of the line and better than what else is currently out there (in terms of single GPU) but don't let anyone ever tell you that current technology is "overkill" when it can barely play some games even at just HD res. I say if you're going to be spending that much money, just go all the way, either GTX 480 or HD 5870 will be able to play most games at max settings with 60fps, or close to it.
