I had considered a universal block and heat sinks but I really don't like the look of it.
me neither, thas why I wait out for a card that has full coverblock support and I always try to get the factory reference pcb's. Much easier to migrate into watercooling since the pcb will line up to the block. Unlike what most people have been facing, they just try to mold their blocks into working with their cards.
Might want to look at the 670. The XSPC razer'll be fantastic
* looking into that pcb
** i also forgot you're purchasing from the UK.
