Not really. It's not a big advantage, since just about everyone has similar sensors in their systems. Apple needs all these sensors because they tend to let things run a bit hotter than most PC makers do in order to keep fan noise down. Nothing dangerous, just in the upper range of accepted temps from Intel rather than more middle of the road for everyone else.
I'm not really a huge fan of the DVD fan placement, since it's also used to cool the video card on newer iMacs. The older pre-Late 2009 models had the video card heatsink sandwiched right next to the CPU heatsink, and the fan would blow right across the grille for each. And it's certainly better than the old G5 PSUs, which were at the very bottom of the system and the only ventilation was from the bottom. An old boss of mine called it 5lbs of <excrement> in a 2lbs bag.
One thing I will say, is that Apple has some very talented system designers, and the way the company is structured, is that the system designers tend to be the project leads. They are involved in every aspect of the system, it's not some bunch of marketing people who just toss out a bunch of unrealistic ideas for things to add to a system. The system designers at Apple are the ones who deserve the title of Genius, not the idjits who work in their retail stores.
But it's not a huge advantage really. Everyone else is just flat out incompetent at making all-in-one systems. Dell, Sony, HP, Acer... Pure garbage. As annoying as the iMac can be to work on, those things are even worse.
I've been using intel iMac core2 duo. There are some temperature sensors to HDD, CD/DVD and CPU... etc, I think. Apple computer is well designed for thermal control and is this big advantage for technical point of view ?
