Hi! I see parts are expensive in Australia. Okay, I will provide you some rough ideas that how a gaming build may look within that range of your budget. This build is meant for 1080p gaming and cooling will not be an issue, but you will find some items that are added which will allow if you want to upgrade your system in the future without paying extra cost. No OS is added, check with your local stores if they have cheaper prices. As this is just the build, but at last the decision is yours.
