Full cover liquid cooling for my custom 670

I have a gtx 670 power edition and I was wondering about liquid cooling this beast since ill probably get a second one in august (birthday) and id heard that graphics cards can get pretty damn hot when in SLI. However I recently came across a forum post where someone said there were no waterblocks for this card, and that you could only get ones that fit directly onto the core and not the rest of the card. Im fairly certain my card uses a pcb similar to or exactly the same as a gtx 680 although I cant back that up as I cant remember where I got that from. Does anyone know of any for this card? it is an msi gtx 670 power edition. http://www.msi.com/product/vga/N670-PE-2GD5-OC.html

Thanks for any replies, this will be my first full loop liquid cooling (if there's a water block out there for my cards)
