I actually finished the build a while ago but I waited until I got a new chair for Christmas to post this, and since it's Christmas I'll keep this short.
CPU: Obvious choice right now since it seems the new stuff on both ends isn't coming to 2017. Good chip for a good price and overclock-able, so all good there.
CPU Cooler: This is where I had to make a tough call that was only made easier by one thing, stock. It was this or the slightly more expense CRYORIG H7 and the H7 was out of stock at the time forcing my hand. I still like this cooler though, well except for the mounting bracket that was a pain.
Motherboard: What can I say about this choice other than it's a Z17- so overclock capable, it's got a m.2 slot for when I want to put on in eventually (whole reason I bought a MB with that), and its price was pretty good.
Memory: Simple choice really, I know Corsair has good ram and this was cheaper at the time than it is now.
Storage: Duel wielding on this one. 1st: My boot drive as well as main programs drive this ssd has got good speed, I always get a fast boot up and it's a good option for those whole don't have or don't wanna spend the money on a more expense ssd. 2nd: The old reliable around these parts, the WD Blue 1TB, I can't say anything about this that hasn't been said already.
Video card: Now this is where I have to defend myself a bit, not over the choice, but over the price. The online prices at the time were still pretty high for every model of 480, 4g and 8gb, and didn't drop until after I picked this up on a whim at Best Buy.
Case: I almost went no silent, but I spent a little extra, and I'm happy I did, I love this thing, and I love the it's so quite I can barely here the fans on low as i type right now.
Power Supply: I always liked EVGA's units a little better than others, and I never knew why at first. The I did research and I loved them even more. Apart from a few there so consistently good. This one and many others being JonnyGuru recommended.
I also have the following to help complete the Knockout: Headphones: Logitechg430 (I had Razer headphones, for a bit but they stopped working in one ear) Razer naga mouse and Razer deathstalker, and an AOC 22'' IPS monitor.
Also I only two two pictures of parts before building, I tried to take a lot of window shots though so you can see what's inside so sorry if some of the pics look the same.
Have a nice day bang bang.
