Acer Aspire 3627WXMI @ Officeworks $909
The spec is fairly low end and 256 meg of RAM is pretty boring. But having said that the price is a bargain by comparison with everywhere else I can find the same model so you'd be able to buy it and upgrade to a decent slug of RAM and still be in front.
Cant deeplink into the Officeworks site so go into their > clearance centre > 30% off > tech products. Only thing to watch here is that they dont do a 30day return warranty on these sorts of clearance items. They do give a DOA obviously though because they are obliged to by statute.
If you buy grab a freebie - just because you can - we know you dont actually need any of this stuff...
