1. Sign up for Newegg's email subscriber promos. I just saw them recently dropping the 8700k to $330.
2. An NH-D15 is totally unnecessary unless you want to OC. I got a Cryorig H7 for my 8700k and it's great at stock speed.
3. That case only has 1 fan top and 1 rear, and you're spending a total of $170 on it and fans, which should buy you something MUCH better regarding airflow. Solid front panel cases are a bit quieter, but hotter.
4. A 1070 Ti only requires 550w, and that's total sys power and conservative. So you're spending too much there too.
If you hit better deals and reconfigure a couple parts, you could potentially save as much as $200 and get a much better GPU and/or more storage. 500GB gets eaten up really fast these days.
