Well FYI I have some feedback on ASRock mobos … don’t get one, go with something like ASUS or Gigabyte.  I have spent the whole weekend fooling around with the BIOS trying to get the CPU fan to spin properly.  I won’t bore you with the details but ASRock evidently have issues causing the CPU fan not to spin at all unless it’s going flat out – no good for a quiet HTPC build.  Anyway, I have it performing better now but not completely as it should be working.  Save yourself the hassle and buy a better brand.  
Shame about the price issue … we get screwed over here too but not as badly as you guys I’m sure.  Maybe try newegg?  They ship to Aus now, I don’t know about NZ though.  The VR setup sounds cool … good luck with it.
