For spending all that money the SSD is a rather low end entry one, and its small at that. You should get something larger and faster there are some new OCZ SSD's, and even the previous generation would be better than the 64GB SSDNow.
That RAM speed is rather crazy, you would be better off with something a little slower and tighter timings at least when it comes for bang for your buck (or euro in this case).
So, before ya think it, you're gonna say that you can always add another 590 ... and ya can but to what end. Adding a 2nd 590 scales only another 14.6 % and $700 is a lot pf moola to pay for that piddling improvement to 982 fps. If ya now thinking 6990, that card scored 762 fps in the same text, only 903 in CF.
Looking at alternatives to the 560's, and based upon total fps in the same game set, ya have the following choices (single card / SL or CF).
Cooler - This isn't my 1st choice .... fr max performance I woulda went with the Prolimatech Genesis or the Thermalright Silver Arrow. But user wanted to be able to add RAM at a later date w/o messing w/ cooler and the Kuler was only off the "record holder" by 2.9C. Here's two recent test results (test uses single hi speed fan for all tests to take the fans used outta the equation:
Corsair H50 68.1
Coolit Vantage A.L.C.
Corsair H70 64.7
Coolit ECO A.L.C. 64.3
Cooler Master V6 GT 59.5
Prolimatech Super Mega 59.4
Antec Kühler H2O 620 58.7
Thermalright Venomous X 58.0
Thermalright Silver Arrow 55.8
Note ya can't compare results from test 1 w/ test 2 as different system used.
TIM - It has the best numbers and no curing time issues.
SSD - 64 GB is a but small for "convenient" usage. I have built many Win 7 systems for people with 64 GB. C:\ drives ..... About evcery 6 months I get a call asking for help "cleaning them out". The V100 is less than half the speed of the Vertex 3
HD - 7200.10 is 2 generations old and therefore very slow by today's standards. If ya willing to spend some extra $, the Seagate XT is faster than the normal "big 3 picks" (WD Black, Spinpoint F3, Seagate 7200.12). Most of this is due to increased areal density. The SATA III interface only has a minor impact on overall seed as transfers from cache will benefit from the 6 GB/s interface but the mechanical drive doesn't come anywhere near exceeding th SATA II bandwidth.
Case / PSU - Nice touvh on that case, adding a BlacX HD docking station to the build.....at $89 on newegg it's an attractive price to0. I have never built with the case tho so I hesitate to say anything else. The PSU however is not a direction I'd go. You have not sized it to handle twin 590's. One 590 or twin factory OC'd 560's will require a very good 750 watter or greater. Since ya can't use the CP-850 as it's CPX form factor makes it incompatible w/ your case, I'd suggest the XFX Black Edition 750 or 850 watters. The Black's get the same 10.0 performance rating as the Corsair HX and AX series, Antec CD and SG series and Seasonic X series .... however the Black's are much less expensive generally than their aforementioned equals.
