I am wondering people opinions on why Apple uses so many custom parts in its computers. For example, they use a 24-pin power connecter instead of the standard 20-pin (and differently arranged than the ATX 24-pin power connector). I am just looking for people's opinions on why the do this? It certainly must add to the cost of design, construction (and as a result the final retail price). Is it just to make it difficult to assemble your own "Mac"?
