A standard machine comes with a PC-screamer and an audio card, but not with
speakers FOR the audio card. Moreover they are usually external.
I can imagine messing with the speaker for cases for public PCs, which are
mostly single tasking. But maybe even then it is wiser to conform, and look
in some specialised vendor's catalogue for an internal speaker that connects
to the audio card.
