Ok look.
Your PC is great, runs any game completely with no lag with a stable FPS which is good.
But in my opinion I don't really like watercooling because if anything goes wrong, it can fuck up your whole PC.
For instance, if a tube becomes punctured, water will probably get into your system and mess it up, leaving you pissed off.
It's a good PC though, very nice indeed. I'm just saying my opinion on watercooling, and you should've got 64Bit because it uses all of your RAM to enhance your gaming experience.
