Nothing special, I bought a Mac Mini about a year ago, things have changed a lot and I don't get to sit at my desk as a regular during the night, selling it seems hard, and Apple just accept a Late 2021 M1 mac mini with 16GB RAM, 1TB SSD for $450 lol. So I decided to continue using it as a headless computer via my iPad instead of trying to sell it.
The image quality on VNC depends a lot on the internet connection btw, even for the same wifi at home, I had to use Adaptive Quality mode for a better experience. There are not so many good VNC clients on iPad, Screens Connect seems to be the best one.
