Yeah no chance in Windows 11 ! 
I'm on W11, I wanted to make a NIC Teaming for a workaround on something, since Microsoft locked the feature on Windows Server, only thing left was the Intel solution, surprise, Intel announced that they will drop the support for VLAN and NIC Teaming on Windows 11. So, if you want Teaming, stay on W10 and use Intel PROSet (can work on any cards). Or buy a managed switch to do the same work.
 
Edit : You can always do teaming, but you will rely on 3rd party software here some project :

No that is true, you can control the air easily in a closed case than an opened case, and provided you have adequate case fans.
I say outside of us PC enthusiast nerds, average home PCs owners majority work with closed cases, not tempered glass and their cases usually lack sufficient air flow, which in compared to an opened bench would be more sufficient.... but if the room temperature is warm, then it's going to nullify any benefits of an open case. 

See my open case here, system temp is 35°C , where as my closed case shown below, system temp is actually cooler at 30°C.   I try to keep the thermostat set at 74°F.
