I live in a particularly dusty house and in the past dust buildup has been a problem. However with the imac you are unable to easily take the machine apart and clean it properly. Normally I would just take it to a local service center and have it cleaned professionally "that way if someone does get broke then applecare should cover it". However... I do not appear to have a certified technician or apple store in my area. At least not one within reasonable driving distance "the closest one is easily a good 5-6 hours drive". Does anyone else have experience with this type of thing? What is generally the best way to handle this?
