I am looking to buy the Thermaltake BigWater 12cm water cooling kit. It is very inexpensive and I dont quite have the time to piece together my own setup. But this kit only comes with a CPU block. Would it be a good idea to consider adding a GPU block and chipset block to the package? The BigWater pump flows at 120l/hr, would that be enough to cool all 3? Im a noob to watercooling(havent owned a setup yet, but have done a lot of research) and would just like some advice. Thanks!
