If you're willing to mod, the FT02 is surprising flexible. That, and the R3 essentially demand modding to make the most of them. For non-modding, the other two can do at least about 240.2 rads in stock form, though you may need to place a set of fans, or a rad, on the top side of the case.
Don't take this the wrong way, but $1,900 build where none of it is eaten up by a monitor or any expensive boutique parts, yet there's a single 6950, Arctic Silver 5, Corsair TX, and a Hyper 212+? No bueno.
The OCZ SSD is also debatable. Looks like a few different members have already offered some good advice.
Like TheExodu5 said, it has the same amount of memory as a GTX 570, with 570-like performance. What's often overlooked is how the lower-priced, after-rebate 570s are mostly reference cards, and cheap custom models. That includes stock 570 VRMs, which can be problematic. For the same price, or lower, you get a quality custom 560 Ti 448 like the MSI TF III Power Edition. No rebate needed. There's little guidance on the 560 Ti 448s, so even lower end cards are nearly all faster than the loose 448 reference spec.
The Raven has better build quality, and stock cooling performance, but your plan for replacing the Arc fans is a good one. A lot depends on your selection of components. If you intend to run more than one non-reference cooler type, high end GPU, you have to take care in how you setup your airflow. Proper airflow setup, along with good component selection are far more important than gravity, or convection, in the majority of instances. For ~$112 at NCIX US, I'd also say to take a look at the Antec P280 (if non of the other OP suggestions work for you):
