This cool, but can we get an option to emulate HDD noises please? I really miss the whirrs, clicks and creaks. And the little LED that indicated disk activity... but that'd be a separate project.
I suspect the noise is caused by the power supply emitting a tiny bit of 'coil whine' when put under more load
The "Fast, Cheap, or Good... choose any two..." joke is very real. =3
