Any reason you want that noctua cpu cooler? You can probably get the cheaper CM Hyper 212+ and get good results.
 I never heard of that RAM brand, Avexir. I hear they're a big OEM manufacturer so it might be okay. But with big names, it might be easier to get support if something happens.
 I don't really know about that EVGA PSU. It got good reviews from GUru3D and techpowerup. It is made by FSP Group which is a quality manufacturer. I am not sure if it is worth the $100+.http://www.techpowerup.com/reviews/EVGA/NEX750G/http://www.guru3d.com/articles_pages/ev ... iew,8.html
