I had to sell my kidney to get that RAM :D , 1650Eur
For cooling i did change my plans too and went for 2x360 rads.., should be good up to 800W at 10 Celsius delta... , heatkiller iv pro block
For case, R6 was obvious choice, i have R5s now , But then i saw Phanteks Evolve X and i just could not resist , looks amazing and more space on top for rads then R6..
