Quick Question, regarding silverprop gpu block and x1800xl

[Kamz]

Hi

i wondered if anyone had experience with this gpu block and if it would fit a x1800xl, i have been on there website and it stats gfx6800+ compatible and i think thats the same set up needed for the x1800xl.

However i dont understand how many addond clip assemblies i need to buy, anyone here have one on a 6800??? or x1800xl??
