Motif Monument is an open chassis / test bench perfect for unobstructed convection and passive cooling. Its structure is made of "just 2 pieces of 3/16” steel that are cut, bent, welded, and finished to the highest possible manufacturing standards". This particular build features AMD's Ryzen 5 3600, GIGABYTE's GT 1030 Silent and Nofan's CR-80EH CPU cooler.
Update: Here's why we don't recommend the Nofan CR-80EH. This thing can't handle a 65W AMD processor (desk fan necessary)
