I'm with Bojamijams on this one. Yes we need one Vincent :) The NB's fan is awfully loud! The EVGA 750i and 780i PCB reference board is so close.
EK's 780i's NB block fits the 750i's, not 100% because obstruction of the nut that came with the block, but the holes line up perfectly, and it will still work if you just leave the nut out...I hope you'll be able to find one, I'm thinking it might fit, but who knows there might be some capcitor that could destroy our hope...
