Hi, in order to have a 100% silent computer is it possible to use a Mac Mini G4, 1.42 GHz: 1) without hard drive (start up with a silent external FireWire 350 GB LaCie mini disk). 2) without CD-DVD optical drive (using, of course, an external high quality and silent LaCie CD-DVD drive). 3) without any fan (I would like to remove the fan because I don't want to hear any noise). In order to refresh the Mac Mini and keep it cool, I would not replace the external top cover, just leave it open, allowing air to naturally circulate. Do you think it will work for more than a few hours, or will it take fire? Is someone out there who tried to have a silent Mac Mini? I am a Mac Cube G4 450 GHz user. Cube it is totally quite, but it runs too slow. That's way I would like to have a silent Mac Mini. Please let me know your opinions. Thanks.
