But I hope your page was simply humoristic and ironic ?--[[User:MacDeath|MacDeath]] 18:07, 23 February 2010 (UTC)
:it is both, ironic and serious
:cassette and disk drives are inside of the case, it's barely possible that dust creeps in there. and if it does, this would be only a problem in zero-gravity environments, on earth, gravity lets the dust particles drop down before they can't settle on mechanical components. even if some should glue to oiled mechanics - doesn't matter very much
:overheating wasn't a problem in eighties, it came up with 66MHz era, whereas these newer "overclocked" computers have ventilators, so the dust gets blown away from hot components.
:cleaning a computer every 3 or 5 years is a good idea. warranty is a thing addressed to amateurs, saying "keep your fingers out there". and warranty lasts only a few years anyways.
