I’ll cut to the chase. When the system is turned off, my mobo still has two lights on, one to indicate power and another for some sort of status thing. When I come somewhat close to the system, with the side panel off, I hear a small buzzing sound from the psu when the system is “shut down”. Is this normal?

Actually that is quite normal with cheaper power supplies. If you ever plug in a dual port charger for your phones or tablets, you will here a slight buzzing sound. Or maybe it's just all the products in my house. Or my house.
