So, Im in the process of converting my movie collection, currently in .dvdmedia containers on an attached HD, to H.264 files for my iPad 3G. Based on the size of the collection, it will at full load/100% CPU use for a month or so cranking 'em out. Depending on the specs of the 4G iPhone, it could take another month or two for those conversions; so Im looking at keeping the thing on full use for perhaps two or more months. So I dont melt down my laptop, my SOP for rendering is to use a current generation Mac Mini 2.26 GHz model (w/ Apple Care) that I have dedicated to task like this. I keep it raised on a wire-grading shelf so there is plenty of ventilation. Part of me does not care if its damaged; the files made go to the attached hard drive, its not a mission critical computer, and its under Apple Care. Im more curious on this, is it possible to damage or destroy a system using it at full load for months?
