== Legal Status ==
There are no known laws against producing, distributing, or even using dust covers. However, one is likely to lose any warranties if a computer catches fire because of covering its ventilation holes after forgetting to previously switch off the power-supply. Fortunately, the dust cover users never realized that dilemma, otherwise they'd have probably died from a heart-attack when trying to find a solultion to the question: risk the warranty? or risk the dust?
