I’m fine with the dongle because all I ever use the headphone jack for is for listening in my car (no bluetooth), so the dongle just stays on the end of the aux cord in my car.

No dongle would obviously be better, but it’s a very minor inconvenience for me,

Yeah, those are the only ones I see that I’d be able to justify with your requirements. (and two of them are ones you mentioned)

For cases with a solid metal or acrylic side panel, you can always just make space for fans on them.
