"Funnily", the only motherboard that has a type E / USB C header is the ASUS Crosshair VIII Impact, but that one does not support a custom loop in the Ncase. I received the MB and RAM yesterday, it's all pretty and shiny and RGB, but clearly a lazy job on ASUS's side to make it DTX, a clear middle finger to many SFF cases. The DTX part has the sound and extra SATA ports, neither of which are useful to me, headset is USB, and I use NVME only.
