Just a heads up. Nina is awesome and what I use but it's part of a suite of software that you need. Cuiv has a great video on the whole process.
ASCOM (general astro equipment infrastructure)
PHD2 (for guiding)
ASTAP (for plate solving)
ASTAP Database
NINA (which will also install .Net)
Than you need equipment drivers so in your case the ZWO suite and the manager for your AVX.
If your Dew heaters are 12v and run off of the ASIAir, you will also need a solution for that.
You will also have to enable remote desktop on the mini pc and ideally give it a static IP on your network. You may also want to invest in a travel router depending on your use case.
I am not trying to discourage you. I love and use NINA but giving you a heads up to some potential things you have to over come if you have never used anything but the ASIAir.
