I wouldn't bother with the extra 2gb on the 680, it's only useful if you're doing things like triple monitor setups or doing some serious modding on things like skyrim, so save yourself the cash and get a 2gb 680, or if you really want 4gb you could look at a 4gb 670 as it will only be a few fps off the 680.
For that money I would look at a modular PSU, as the corsair you specced isn't modular...
The Raven already has fan speed controller for it's 3x180 fans, the older Ravens were more noisy but the updated version (the one you've got) has got better fans and you can't hear them when it's on low... and I challenge you to find a case that's as quiet with the same cooling prowess, it's also one of the best air cooled cases out there in terms of cooling potential.
