Jobs wa never known for engineering products for form over function with disastrous results -- i.e. the Apple
Interestingly, the widely-propogated assertion that the Apple III's vent-less, fan-less case (pushed by Jobs) was to blame for its exceptionally-high failure rate has been disputed.
From the Wikipedia "Apple III" article:-
Case designer Jerry Manock denied the design flaw charges, stating that tests proved that the unit adequately dissipated the internal heat. The primary cause, he claimed, was a major logic board design problem. The logic board used "fineline" technology that was not fully mature at the time, with narrow, closely spaced traces. When chips were "stuffed" into the board and wave-soldered, solder bridges would form between traces that were not supposed to be connected. This caused numerous short circuits, which required hours of costly diagnosis and hand rework to fix.
