1. Change that board. YOU DON'T NEED A 300$ BOARD. An Asrock Extreme4 P67 is good enough. Also as Omni said, wait for the SB fix. Don't jump into it.
2. Omni, I believe he isn't in the US.
3. Drop the 430, that's a terrible card. It wouldn't even be good for Physx, it's worse than a 250 GTS.
4. HX-750, that or a XFX 750. That should be enough.
5. Drop that cooler, a Hyper 212+ is cheaper and a better price/perf cooler. 32nm doesn't need fake water cooling anymore. The Hyper 212+ has many people saying they've OCed their 2500K's to 4.6ghz+ (Depending on CPU grade. Not all chips are made to the same efficiency)
I just saw your post. Drop the 800D, pick the HAF X up. Just as good and it'll save you a bunch.

That or the HAF 932. Either saves you almost 100 AUD.
