I'd like to thank my friend Pawel Badziak for his help and consultancy provided during both project and building phase.
I use stock CPU Cooler, and CPU itself is not yet overclocked. I don't use as much power, and all games I use it for don'r exceed 60 fps. (due Display). I'm happy with such result, and I don't plan to change it as long as 4K gaming displays are so expensive.
RAM is not to big for this build, I got lucky and bough exactly the same model as provided in the List. It fits.
Hadron air was the must in this build, I wanted to have console size gaming PC and I have it. I could only accomplish it with GTX 980, best GPU available at the time.
If you thing 500 SSD is not enough, well. I'm not hoarder for files, and with Internet speed 100 mb/s, there is no need for HDD.
My read write speed is 6 gb/s, thanks to Samsung software. AND I LOVE IT :D I don't even see Windows welcome screen on boot :P
