oh epic - cant wait, i kinda watched the video for the installation of the aqua computer block and decided that it was too much effort dealing with a backplate, the DD installation guide was quick and simple so it climbed to the top of my list...

Anyone want to guess the order of performance of the blocks? My money is on the swiftech & dd blocks being the top two performers, with the koolance & ek being close seconds, and that the BP block will be the worst of the lot...
