It’s been a while since I read that classic of heat transfer Hot Air Rises and Heat Sinks, but I’d worry about pockets of air getting stuck around important computer components. Like, sure there’s a lot of air going past things on average, but not necessarily around the things that get the hottest.
Surely normal cases have some kind of ducting considerations to pull airflow through more effectively?

An open case like this will generally be the coolest, the reasons you don’t do this are dust, noise, and just generally protecting the components.
