So what waterblocks are being used? I saw the DD Maze mentioned, trying to decide if I can't wait for something else to go with either some low profile maze 5s, or see about the Fuzion GFX 2, if/when it comes out, though the mazes are cheaper. That's about the only drawback I'm concerned about with getting a pair of 4850s, is having that heat sitting in my case if I don't watercool them, at least my 8800GTX shoots the hot air out the back.
