Welcome to TekSyndicate :)
Yes, there are a few things I would change. First of all, the biggest thing I don't like is the PSU. XFX is known for generally skimping on the quality of the PCBs (Printed Circuit Boards), which could end up screwing your system over. For not much more, you can get a good Corsair or SeaSonic fully modular PSU that will be much better quality and extremely reliable. Remember, the PSU is one of the few things that you will be carrying over from build to build, so don't ever skimp on it. The wattage is good, however. You won't ever use more than 750W even in 2-way SLI or Crossfire.
For that money on the RAM, I would get 16GB (2x8) of DDR3 G.SKILl Trident X 2400mHz memory. Here in the states, it costs $139.99, so it is even cheaper than your HyperX memory you chose. Also, a side note - I think that HyperX memory is horrendous, but that might just be me ;)
That Samsung SSD will be good, but in the Samsung product chain, the 830 is better. The quality/speed goes 840, 830, 840 Pro. A good alternative is the ADATA SX900, which is about as fast or faster than the Samsung 840, but much cheaper, especially for the 512GB model. I found that my SSD (120GB) filled up really quickly. For $190 (about 142 euros), you can get a 256GB ADATA SX900. I would highly advise getting 256GBs of whatever SSD you end up getting -120/128 fills up quickly.
Gor not much more, or possibly the same, you can get a 7870 XT/Tahiti LE, which uses the 7900 series GPU, which is faster and more robust. It is practically a 7930. They can be found all over the place - I know that Sapphire makes one for pretty cheap. If you can't swing that in your budget (which they aren't really that much more), then the 7870 standard (not Super/Overclocked by the factory) is a great way to go; still very powerful for the money.
If you like that case, go for it, but I personally love Fracta Design cases. i have the XL USB 3.0 and it is the best case I have ever built in. The new Fractal Design R4, which is a standard mid-tower caes, is about the same price as the one you chose, but I think it looks much better. I don't have personal experience with the one you chose, but I can assure you of Fractal's design and build quality, especially in the R4 and XL R2.
Also, just a quick question - why are you buying two 1TB HDDs? You could save some money by just getting a single 2TB HDD and putting the rest into a larger SSD. And, just to giver perspective, I bought a 2TB HDD when I built my new system. I have been torrenting like crazy (legal stuff... yeah...), archiving audio and film, and still, I haven't filled up 500GB. If you just get a single 1TB HDD, or a 2TB which will be about $20 (~15 euros) more, you could fit room in the budget for a 256GB SSD. Or, if you want, get rid of the HDDs entirely and get a 512GB ADATA SX900 SSD ;)
Overall, the build is very well thought out. There aren't many things I would change. Still, if you built it as is, it would be a very nice computer, but there are ways to make it better for little or no more money. Cheers and welcome to TekSyndicate!
