The Computer Repair Screw and Standoff Kit contains all those bits and pieces that get lost whenever installing stuff into your computer or electronics devices: the screws, standoffs, washers and more that are used for the chassis, fan, motherboard and component extras. They may also be used by other electronic devices around your home. Particularly useful if you are working in IT, but also handy if you're the kinda person who keeps their tower with the side panel open, you'll reduce rattling and avoid sitting parts on top of other parts when you have the right mounting hardware!
