Comes with Windows 10 Pro but you can save an additional $111 ($1130) by opting for Windows 10 Home. Ditch the crappy keyboard and mouse and save even more.
Doubt I would ever pay the original price but this price point may interest some.
They also have an OptiPlex 3050 Micro (i5-7500T Processor | 128 GB SSD | 4 GB) for $971.10 (Originally $1,431.10):

Yes its not a gaming PC, Yes you can make your own for cheaper, and I think Lenovo sell a similar model for about $1200 but I have 3 Dell PCs at home and have never had an issue. So if someone wants a prebuilt small form factor PC I think this is a good price. Otherwise look away.
BONUS: If you have an ABN you get 8,888 Qantas Points apparently.
I think you're better off getting a refurbished Optiplex 9020 or 9010 and just chuck a SSD in it if it doesn't have one already. Will probably perform the same on day to day task.
