Everything seems fine. But if you plan on getting a Hyper 212 EVO, you might as well get it now, as it requires you to take the motherboard off from the case.
For your GPU, since you will wait a few months to buy, I would recommend the Radeon 7850. It performs just under the GTX 660 but you can pick one up for around $175 right now. After the new 8xxx series comes out this winter, it should fall to around $150.
Also, Microcenter is a very reputable brand. They have many stores here in the US. I have no idea why they're CPU's are so cheap, but it's probably because they are only available for in-store pickup.
