Looks alright.Also that surge protector will protect against local grid surges but I recommend unplugging any telephone wire/broadband cable lan wire to modem/router if it is connected to pc via lan wire(no issue with wifi) during thunderstorms as no surge protection will be enough in that case(except for the whole house lightening surge protection which is costly & may not be possible to do at all depending on house). Use speakers in that surge protected socket.
