Interesting!

Maybe I overestimated the overhead of the pc-speaker sound driver. Still, the quality is dubious due to the hardware. Some case designers fit the cheapest possible speaker / piezo-electric device in order to minimize cost. (It is only used for system beeps so why use something expensive. Who cares if there is scratching on a beep due to somthing located too near the membrane...)
And don't even try asking a pc-case salesman about the quality of the built-in speaker.
