This tiny ~3x1" medium-blue plastic box was provided with my ASUS a8n-sli motherboard; any idea what it might be?

It has two, small, two-pin connectors on one side, an even smaller two-pin connector on the other, and when opened, there appears to be some sort of tiny-circuit board in there.

have a look at this and see if you can see it there

Nein, not there. It might've come with my videocard, soundcard, or HDs, or anything...

Any other ideas?
