Hey. First of all, what is a good universal GPU block, if there is one? I have a 6600GT now, but will get a 7800GT later, and would like to have a block that fits on both. Secondly, you guys need to make a sticky that will get rid of annoying watercooling questions like mine. If you want, try out some ideas on this thread. I am happy to share my knowledge and experience about the components that I have. I know you guys have talked about a wc sticky for a while, but it would be nice to finally have one. Hopefully, no one would have to do too much work if only everybody would contribute their personal knowledge. Thanks
