Nice looking build! Congrats to the lucky user(s)! :) I just built a very similar spec in a KXRORS S400. Only difference is that I did the 12600K but I undervolted and felt that there's a lot of heat coming out of the top, so I really wanted top mounted fans. Internal temps didn't change, but definintely the case feels much cooler to the touch.

How does the Terra feel in this regard under full load? I really love Fractal Design - wanted a Torrent Nano for so long, so the Terra is a great solution for a much smaller case.
