Yes, that's sold as a DIY computer, so getting it a case is a must. OTOH, I'll be honest and say, both the official cooler and official case for RPi allows it to run at full-steam, almost all the time.
I especially bought that passive case for my Pi, because it's destined to be a "tuck away server" from get go, and it's trucking along just fine. I'm adding services on top of it slowly, and it's not showing any signs of fatigue.
A2 card and faster SD support really makes that one shine, without adding hats on top of hats. Again, OrgangePi 5B has better hardware, but way worse support.
