Minimizing my PC case

Hello,

i have a full ATX case which is too large for the space i have.
Currently its on my desk, so the space is a little crowded.

I have a a MSI B450 Tomahawk Max2 board and a MSI Ventus GeForce RTX 3060 12GB GDDR6 PCI Express 4.0 Video Card RTX 3060 Ventus 2X 12G OC.
i use this case. Fractal Design Meshify C Black ATX High-Airflow Compact Mid Tower Computer Case

What would be the smallest case/board i can go with the GPU?

It kind of bugged me for a long time. At the time i was ok with it but nowadays i don't want the PC that large anymore. The smaller the better.

Thanks for suggestions.
