Please review my first build.

I think you've done really well there, I like it a lot.
Only thing I might suggest is low profile RAM, those RipJaws can cause problems with coolers. You're probably alright with that MB and cooler, but the G.Skill ARES series are a better choice.
Either 1600Mhz for the same $99 you already have - http://www.mwave.com.au/product/gskill-ares-8gb-2x-4gb-ddr3-1600mhz-desktop-memory-f31600c9d8gao-aa65874
Or 2133Mhz for $6 extra (note that they are 1.6V though) - http://www.mwave.com.au/product/gskill-ares-8gb-2x-4gb-ddr3-2133mhz-desktop-memory-f32133c11d8gao-ab53984
Nice build!
