I was thinking of how I could create an easy, safe way to drain my future wc'ing loop. My plans are to place a rad at the bottom of my corsair 800D as you probably have seen, but instead of using normal fittings I could use koolance quick disconnects. This will allow me to detach the tubes without spilling, hang them outside the case and then remove the quick disconnects that way it all drains outside the case. Also it will be at the very bottom of the loop so it should drain fairly easily. Do you think this is practical? Or is there a better way to do this.
