Hi, just to start, Amazon does ship to NZ, BUT if you need to send something back due to faulty parts (i.e. DOA), you foot the bill to send them back to the US. Check out computerlounge.co.nz and playtech.co.nz (I bought my parts off them). Also, check out pricespy.co.nz to see which NZ dealers are cheapest.
Can't really say much else until you look a little more local. You are missing a CPU cooler. Get the hyper 212+ or wait for the evo to come out.
