CCPU (Carlingford) have the 2TB Western Digital Caviar Green 64MB cache 3.5" internal drive WD20EARS for $165 in-store. Not sure about stock, and not sure how long this price will last. If you buy in-store, you may have to mention you saw this price on their website.
I enquired about shipping to major capital cities, and they quoted $15 (for one drive).
They also have the 1TB WD10EARS for $85, which is the same cents/gig.
$169 at msy?
