See, I'm Australian; will I find a difference in the price?
Also, I'm not experienced with buying stuff online; what do you have to say on the matter?
And I think that's about it.
Krunk, take a look at this store: link [http://www.msy.com.au/] (you can have a look at store locations and part prices). It's a physical store, and it's located quite a few major cities (all I'm aware of is the Sydney one). I find them to be pretty cheap, but it's pure wholesaling; don't expect them to help you build anything.
On the other hand, you have these guys [http://www.bigbencomputers.com.au/]. They're alright, and they'll build the computer for you, but they mark up rpices, so expect to pay more. I've had them fit a new graphics card and some more RAM in, and they're alright.
Hopefully, this helps.
Edit: I've been looking at looking to build my own rig for some time, and so far, for a decent rig (E8400, MSI P35 Neo, 2GB DDR2 800, 512MB 9800GT), I'm expecting to pay about $AU800 (take into account that fact I'm also getting a 19" monitor along with the thing).
