Mini Build for Fusion

I’ve only built one PC in my life, it was a fun experience. I’m looking now to build a small form factor PC to run Fusion 360.

I’m not familiar with motherboards and hardware that can be used is SFF builds so I’m looking for some help.

The biggest challenge I see is the GPU as most have a large form factor, but I think a mini ITX could house an RTX-2000 (forgive me I have details wrong).

Lastly, I want to run an AMD chip.

I know it’s a big ask to help a newbie out so I appreciate any guidance.
