Sure here you go. That's including the CPU and HDD if you decide to go the "everything from Scorptec" route, I'd probably get this and this from Amazon instead unless shipping the HDD on Amazon makes that come out to be more than just including the HDD from Scorptec. I'd do whatever's cheaper on the HDD, the CPU I'd probably go with the 2700X which Scorptec doesn't have, but your call. If you decide you want to bring the price down a little that CPU wouldn't be a bad way to do so.

Another thing you could do to bring the price down if you'd like is go with a non-modular power supply but that makes building and cable management a lot more of a pain, plus generally isn't great for airflow since you'll have a bunch of unused cables jammed in your case. Semi-modular wouldn't be bad either, but at that point it probably is going to be very little price difference from fully modular.

And again I just picked a cheap case with good reviews so if you'd like a different case I'd just look for any ATX(not mini-ATX or micro-ATX) that you like that has good reviews and make sure it's one that you can put two case fans on the front and one in the rear.

Edit: By the way I just googled and put in a random Sydney, Australia postal code to see if it would offer free shipping or anything, the cheapest shipping it offered was $35. So if your actual shipping isn't far off from that then that's not too bad.
