More than a box of screw bolts
Most computer geeks have got some sort of drawer with screw bolts to mount computer parts. That way one is never without the right bolt when needed. Nexus sells en pimped version of such a drawer, aiming at those that want to keep their computers quiet. The Nexus Anti Vibration Mounting Kit is a plastic box with compartments, in which several different materials for attaching hardware are stored. In total there are about sixty materials in the box. Quite useful.
