this seems v cheap for a 2 bay NAS which INCLUDES 1x2tb hard drive! my guess is that this is the rnd2000 model.
i couldn't find this on their website - only in their latest catalogue. so not sure if this means you can only buy in-store.
the diskless version is $185 (http://www.mln.com.au/product/?itemID=3426). scorpion technology have the diskless version at $165 - with a $30 visa cashback offer too (http://www.scorptec.com.au/computer/32529-rnd2000).
they also have a diskless 2 bay buffalo for $139 (http://www.mln.com.au/product/?itemID=3994) which is also a pretty good price (same price at scorpion technology too).
called them and they says it's true.
howerver, the unit doesn't look like that.
hmmm….
