Even if it is, which I doubt, do you really want to run a pre-set miner? Where would you get your mining reward?
Just so we don't go with interpretation of what "set-up" means, and judging by the OP, it's pretty clear he means some installation of a certain software/firmware, which in that case, you are wrong because all miners today are indeed pre-set.
will it be pre setup to mine?
The asic miner in the link you posted is T9+ by bitmain, yes it comes ready to mine, all you have to do is fill these 3 fields
The password is usually just "x" for most pools, the URL is something that the mining pool you join will give you, and the worker name is something you set in your pool account, pretty straightforward and takes no more than 2-3 mins to get it up and running.
With that being said, 1.2k for antminer T9+ is way too much, this gear is now worth about $200 or less in China including a PSU, so the max you should pay for it should be below $300, it's not effienct and if your power rate is above 2-3 cents you won't be making any profit, and it runs pretty hot as well, but it's a good learning object if you just want to start with it, however, do not expect to become rich mining with that old gear.
