I've checked this out many times and used precisely calibrated equipment when measuring the effect of taking the case off, and in every incident, the
system ran considerably cooler.
This doesn't mean that everyone will find this solution practical, let alone, feasible. Having an open case on the floor can be downright dangerous
and will not be an option to many.
As you stated correctly, the case - when fitted - does allow the flow of air to be controlled more accurately and thus more efficiently.
However, drives generate buckets of heat and can easily overload the confined space of the case on a hot day.
Even with a Lian-Li case designed for high airflow, the drives can raise the case temp considerably. This sparked a number of gamers in the late 90's
(myself included) on experimenting with esoteric cooling systems. Everything from R45 refrigerant to water cooling and anything in between, including
combinations of the two were tried.
No matter what we did to cool individual components, the over-all case temp was being dictated by the drives and to a lesser extent, the power supply.
This has a big effect on mobo components like the HDD controller which usually don't have their own sinks to shed excess heat.
The solution, was to run the system with the main cover removed so the heat generated by the drives can escape instead of being dragged through the
main cooling pathways.
It also helps to separate the drives (leave space in between each) so they can breath a little better.
