Yep, I emailed EK on the 560 release day. They replied almost instantaneously
After a lot more research I've come to the conclusion that there is only one reference GTX560 and it is not Gigabyte (i won't name the board). Practically every manufacturer has produced a custom PCB layout.
Hence the way forward is thus:
(a) Purchase the reference GTX560 card and get the EK full cover block (but I'd rather have the Gigabyte). This incenses me a little as the cooling solution influences my card choice.
or
(b) Get the Gigabyte (OC or SOC) but only be able to water cool the GPU and have to use Ram and Mofset heatsinks and perhaps use a fan near them (messy at best).
There is a third way, stick to air cooling which cuts out the cost of water cooling and is a lot less hassle, but where is the fun in that eh ? Also it starts to get very noisy, I'm used to laptop levels of noise from my system
