I have done a LOT of research on the issue. With the exception of the heatsinks, transistors, chokes, caps, and such. Yes i can say with much confidence that it is a reference board with better parts added you should have no problem liquid cooling this card.
*As long as you use the right cooling blocks*
Sorry had to add that

I am waiting on today's delivery of 2 right now. So i am with ya.
I do talk to others that are already using liquid coolers on them too.
Good luck and hope it helps.
