All of which seems to be the perfect solution. Yes, three sided

I am not so sure about the rules but every professional installation
I have seen has had an easily accessible isolating switch. I suppose
if an earth fault develops and the casing becomes live or something
catches fire you have no means of killing the power if the only means
to isolate it is behind the cowl. Maybe Adam (ARW)may have a
definitive answer?

In the case of a fan, the switch is there for maintenance rather than
emergency isolation. So it does not need to be readily accessible or
especially visible.
