The Heatkiller block has G1/4 standard size holes which fit any fitting. I am in the process of getting all the parts for hard tubing. When I get all the rigid tubing stuff I will do another video. I'm probably going to go 12mm OD. I'm also waiting for the Bitspower Monoblock for the Aorus Ultra/Master which covers the cpu and vrms. I emailed Performance PC and they will have it on the 18th of this month.
