Finally posting this roughly 4 months after I built this. Took me 3-4 hours to build.
Majority of parts were purchased at a discount during the holiday season.
"Tech Deals" "Bitwit" and "Paul's Hardware" served as awesome guides during my part research, build, and system setup process.
This system is primarily used for gaming, schoolwork, and lollygagging.
The Wraith Spire included with the CPU is an adequate cooler for a mild overclock.
The RAM is overclocked to 2933MHz.
I think the P400S is an excellent case for first time builders. The included led strip is really nice.
Unfortunately, the video card runs extremely loud and hot. (May try to liquid cool it at some point) I use MSI Afterburner to make the fan noise tolerable. Luckily, my headset blocks out most of the noise.
Things I would have done differently is definitely do more research on video cards (Blower vs. Open-air) Also, I think I could have gone with a 1070, but ahh well.
Overall, I'm satisfied with this build. It performs well and suits my needs :)
