If you're going to get an h100i, get a "K" series processor, so you can overclock. Also, a good quality 650w PSU would be plenty for that, the new gpu architecture that the 900 series has is super efficient. Nice choice with the Phantom 530, love mine.
My 1337 Gaming PC: Processor: AMD FX-4300 Quad-Core Processor RAM: 8GB Graphics: AMD Radeon HD 7700 Series Hard Disk: 1TB OS: Windows 7 Ok... maybe not the best PC in the world but it runs the games I play (mainly MC and strategy games) on high graphics and over 60FPS so it does me well. :P
