Acer eMachines: http://www.officeworks.com.au/retail/products/Technology/Com…
These 2 items have not been posted on their website yet but my local store has a few of these in stock :) not too sure about the specs of the emachines but it's pretty similar to the EL1850 if u can confirm with ur local stores; it would be great, it comes with a 18.5'' LCD + a pair of speakers :)btw these USB 3.0 HDDs are 3x faster than USB 2.0 :)
By the way, Samsung 1 terabyte USB 3.0 drives are available for as low as $83 a pop, according to Static Ice
