proudy1032 :
Total price of your system in Aus is $560
My apologies. I tend to assume folks are American if not otherwise stated. I'll work on getting a AU$400 build together for you.
Alright, Aussie PC Part Picker needs to lay off the booze, so I'm estimating a bit here:
CPU: AMD Phenom II x4 965 BE
CPU Cooler: Cooler Master Hyper 212 Evo
Motherboard: ASRock 970 Extreme 3
RAM: 8GB (2x4) Corsair Vengeance/G.Skill Ripjaws/Crucial Ballistix 1600mhz RAM (make sure it's short enough to fit under the CPU cooler. The RAM from my initial suggestion could be used)
PSU: XFX Core Edition 550w or Antec High Current Gamer 520w (whichever is cheaper, XFX if the price is pretty close)
Case: NZXT Source 210
Would that work with your budget?
