MiniPC recommendation

I've never owned my own personal laptop (always used whatever I got from friends or family) and I've never done gaming. So, I need everyone's advice on this.

I don't have a budget for a laptop but I have got dual display setup for software dev work from which I connect my office laptop and 55 inch screen which I intend to use for gaming in the future, if time permits.

Primarily, I want to use this mini PC for development (web, AI and computer graphics)

So, basically miniPC with a powerful processor (preferred Intel) with a powerful GPU (preferred Nvidia). Preferably, from good renowned brands.
