Originally I was planning on using a 2600k but it turns out I checked the benchmarks on every single part except the CPU. At least microcenter has a good exchange policy, considering I haven't opened the box yet. My goal is to have potential for overclock, as well as future proofing. Good card for single card setup, and in a year when it's half the price I can pick up another one. 1100 W PSU with decent reviews should keep everything running pretty well. It's not Corsair, but it does have high numbers, good connections, and 4/5 eggs.
I picked the PSU based on the high wattage which would leave room for overclocking/SLI, as well as the 4 egg rating. Price was also a consideration.
I picked the HDD because it's 6 Gb/s instead of 3, and has larger cache. Granted, I have no clue if either would have a huge benefit, but I figure since my board will have 6 Gb/s sata connections, might as well utilize them.
I would love an SSD some day when I have more money to spend, maybe a few months down the road.
The case has room for a couple of extra fans, however I won't be putting more in until I do some tests with the default setup. I remember looking at some research saying it's best practice to have front intake, back and top exhaust fans. The side fans supposedly disrupt air flow. At any rate, if temperature becomes an issue there's room for an extra 2x 120mm fans.
Also, I should've labeled the thread as a discussion, not a question
