@kenyee And that's because Nanoxia's cases are basically clones -- a very common practice since most brands purchase case designs from the same OEMs. The Deep Silence 2 is a nearly perfect copy of the Define R4. The defining difference was Nanoxia's choice to use two 120mm front fans, which allowed its case to have three 5-1/4" bays, versus the Define R4's two 140mm fans and two 5-1/4" bays.
