Hey there!
I received my 6900XT directly from amd.com a few weeks ago after trying to get a GPU for over 6 month. I now want to get a custom waterblock but the manufacturer wants to verify the board layout beforehand and asked me about pictures of the PCB.
I really want to avoid disassembling my card only to take pictures and then having to reassemble the whole thing just to remove the heatsink again when the waterblock arrives...
Another question on topic:
Does installing a waterblock void warranty if it doesnt get damaged during the install process? I know that EVGA says it is ok to install a waterblock to their cards without loosing warranty.
