Buying computer hardware internationally

[GMI]

For the people that's living in Australia, where do you guys buy your computer parts for cheap (online/offline)? I'm heading over to Australia for a few monthes, and I need a desktop over there (laptop is out of the question, and I can't carry the parts with me, because my flight is in two days and I have no more space in my luggage). Any major company that ships to there and have prices similar to newegg? Monarch shops there, but they charge an arm and a leg for all the hoops you have to jump through.
