hey, its a 1/4 thread... What happened is, i don't have enough clearance between the bottom of my case and the bottom of the water block. So in other words i can't get the tubing to fit between the to areas without kinking the tube. So i need some type of elbow fitting or "L" bend fitting that will screw into a 1/4 threaded EK8800GTX/ULTRA water block and attach to the tubing. Any help would be great, i've looked everywhere and can't find anything.
