The first to get them will most likely be Anyware. They're the biggest distributer in Australia. But they don't sell directly to the public, only to businesses.
But there are a couple of stores which would probably order it for me.
I'm running one of them so far; over the hard drives, the noise is basically nonexistent.
That's why I specifically wanted 19dBA fans, the vast majority are 21-22dBA
The case is finally out in Australia, and I have one ordered (the black version) Aus PC-Market Online eStore
It can be had for cheaper, but that place is the only one so far that has it "in stock"
