Maybe I make big mistake but doesn't d15 blow front to back? If so dont forget back fan location for 120mm. Case vents well so intake side exhaust top. If I was not water cool this is what I would have done.
I go little bit rgb crazy so I have commander pro forgive me. Never have the rgb before, never water cool before so this was fun build. Will say none of it intuitives. Interesting, a little frustrating but still fun.
