Herc08 :
Everything is good. I would recommend getting the WD hard drive. Had many problems with Seagate before. Plus it's only $2 more.
They all come off the same assembly line in Thailand, it doesn't really matter. I would invest in a better cooler though - the Hyper 212 Evo just doesn't cut it anymore. The Noctua NH-U12, Phanteks TC-12PE, or the Cryorig H5 would be far better purchases than that.
All your parts are great, however I'd definitely go with a better PSU.
Are you kidding me? The Supernova G2 is one of the best you can buy right now, it doesn't get much better than these units. You don't need more than 550W unless you're running multiple GPUs. GPUs are using less power with each generation, not more. A 550W should provide plenty of headroom for any GPU you want to run, with some decent headroom for overclocking.
