This is either the lowest price yet or very close to the lowest price according to previous deal: https://www.ozbargain.com.au/node/609302 (note this model differs in that it doesn't support an extra 2.5" SATA drive, but is slightly smaller as a result).
These are very good. I bought on in the last deals couple of months back and I am using it as my plex server. Very happy with it.
