What are people's opinions on Slate Grey vs Obsidian Black? I'm on the fence about which one I like more. The internals on my PC are most likely going to be predominantly black, with a black RGB-free water block, Noctua Industrial 140mm fans which are black with dark brown vibration dampeners and no rgb, etc. Would it look better with a matching black exterior, or do people think more of a two tone look with the grey exterior would look better? I'm leaning towards Slate Grey.
