Mini gaming line disadvantages compared to standard case?

I came across some mini gaming PCs by accident:

Do they have any disadvantages compared to "normal sizes"?

A computer case is used to hold all the components of a computer so that they are not exposed to unprotected external influences.

A smaller case does not bring you any disadvantages, the only thing maybe would be that you can accommodate less hardware.

Jo thank you. They appeal to me very much, there are also those with better components. But I don't have to worry about cooling or anything?
