You forgot the newer i8 cpu. I built one recently with 64 Gig RAM, 2 Tb SSD mirrored drives, and the Nvidia 1080Ti video card.
It is a screamer. I build most of the 10 computers my business partner and I own for our company.
So far all air cooled. The fans can idle along when not needed, and spin up to blow a hard breeze under heavy use. No leaks possible. So far I don’t see the need for water cooling, but I feel that way for 911s as well.
