I went with the very original black/red color scheme - can't imagine anyone has done that before.
I replaced the TIM on the H100i with Noctua NT-H1. Load temps were generated by IntelBurnTest and Furmark. CPU temps never go above 58 during heavy load (video encoding), and GPU temps never go above 62 while gaming. Used RealTempGT to verify CPU temps and GPU-Z to verify GPU temps.
I used BitFenix Alchemy Connect 30cm LED strips for case lighting.
