No speakers please.
For a small daily carrying laptop (work, university, caffe) i dont really need speakers.
Dont forget you cant expect much from small speakers...
And nowdays everyone has some inear headphones around
Also would be awkward if your laptop started playing music in the library :

If u plan to include a motherboard beeper.
Im against a motherboard speaker aka BEEPER, and would either replace it with a led, or have a dip switch (case switch) to enable/disable the beeps.
