Wouldn't touch that with a bargepole..
And fyi most cards released after the initial run of reference cards are not standard..soon as a manufacturer has added there own cooling solutions the cards have in most cases had the layouts altered and full cover W/B will no longer fit.
If you use a W/B made by e.g Danger Den then it's a matter of putting individual passive cooled blocks on the memory. Full cover blocks cool the memory actively and therefore work/cool much better than just a GPU block/passive cooled mem.
The factory made cooling solutions like your link and the Corsair H series and Antec Kuhler etc are second rate at best and serve as in introduction for ppl not used to watercooling. I have a H70 fitted atm to my CPU,it's been modded and quite frankly works no better than the TRUE 120 Extreme air cooler it replaced. I plan on replacing it with a Koolance block.
Secondly the pumps on the prebuilt ones are crap..they work sorta but dedicated pumps work much better. Same story with radiators...
cheers
