As I was moving from Ireland to Canada I decided to take out my newish pc (from my prior build) but leave the case and old crappy wireless keyboard etc behind and use it as an opportunity to upgrade. I decided on the air540 as it is a bit different and I like the look of the cube. The h100i keeps the cpu under 40 degrees even when gaming and the case and twin frozrs keep the 650tis under 55. Im really really happy with the results and from an earlier bench its getting better 3d mark scores than a 680 which makes me happy. Everything is perfect and I am happy with the way it turned out.
