Sorry - was having a snooze
MSY.com.au is my goto for PC parts - are as cheap as they get.
The standard 10xx cards are called the founders edition - each of the brands sell/sold a founders edition (which was the nVidia reference card with their own name on it). In addition to the "founders edition" they sell their own take on the GPU, with different PCB's, designs, cooling solutions and clock speeds. Unless specified under compatibility for the waterblock (http://www.phanteks.com/PH-GB1080.html#compatibility) it's a bit of a crap-shoot - you'd need to confirm the card you're after sticks to the reference design.
