I dont think you can build it. The best option would be to buy all in one cooler that is compatible with kraken g10. Custom loop will cost around 70-80 for gpu block 70 for pump tubing coolant 15, rad 70 and tubing around 10.
Here are details about kraken g10
Compatibility Nvidia : GTX 980, 970, 780 Ti, 780, 770, 760, Titan, 680, 670, 660Ti, 660, 580, 570, 560Ti, 560, 560SE
AMD : R9 290X*, 290*, 280X**, 280**, 270X, 270 HD7970**, 7950**, 7870, 7850, 6970, 6950, 6870, 6850, 6790, 6770, 5870, 5850, 5830
The compatibility list is based on AMD Radeon and NVIDIA's reference board layout, screw spacing and die height only. Please check the height restriction before purchase.
* Some variation in die thickness and height may cause issues with screws being too short to install on some AMD 290-based cards.
* Do NOT force the G10 to fit if your card is too thick, contact support for a revised screw set.
** Some variations in AMD die height may require the use of a shim.

Although custom water cooling kit would look nicer and be quieter
