Er - I'm very sure that's not true. For a start, the 680 PCB stacks the power connectors...
Maybe you're thinking that reference 770s have the same PCB as the 780/Titan?
@OP - according to coolingconfigurator, there aren't any blocks for them, so you're pretty stuck really. Probably have to change the cards if you really want to watercool.
