I'd like to say a few things about your build. While it looks nice, there are other components available that look about the same, perform exactly the same, and are much cheaper.
The Kraken X52 looks good, but man is it expensive. I'm going to switch it out.
I would never pay $210 for 16GB of DDR4. 3600MHz is ridiculous. There's nominal gaming benefit after 2666MHz and that only shows in CPU intensive games. There's really no noticeable difference in any tasks other than extreme number crunching once you get to 3000MHz. I'm going to switch out your RAM.
The monitors you chose do not have prices. They are either not in stock, or PCPartPicker didn't find any stores that carry them. They are not counted in your total of $2542.94 and may not be available on major retail websites like Newegg and Amazon.
The monitors you wanted are currently unavailable everywhere I looked, but I did the rest of the list for you. Let me know what you want done about the monitor situation, since this build is already quite expensive.
