https://www.techpowerup.com/323230/asus-rog-concept-aio-cooler-shortens-the-tubing-with-a-clever-bit-of-design We've all had to wrestle with long AIO CPU cooler tubing to find the right position, and still end up with surplus tubing that sticks out in a U-shape, which looks ugly. ASUS ROG has a possible solution to this. The company showed off a concept AIO CPU cooler based on the ROG Ryujin III, which physically shortens the tubing. The radiator-side tubing terminals are located in a central portion, rather than at the edge of the radiator.
This way, you can have the radiator located along the top panel of your case, or even side-facing 3x 120 mm vents, and there would be just enough tubing to reach the radiator from the pump-block (including clearance with the memory modules). The optimal position for this cooler would still be along the top panel, in our opinion. This cooler would fit nicely into the cable-free aesthetic of ASUS BTF builds, where you can have the radiator terminals facing the motherboard tray for better concealment.
It's an interesting concept.
