What I remember from biology classes was that evolution tends to develop the systems equivalentto brains as close to the primary senses as possible. So brains developed in the head because that is also where visual and olfactory and other primary senses developed at the front of the organism.
It dudn'r deift away because it was alrady successful, but animals with skeletons developed skulls and other thicker bones around the brain to protect it. Same with the rib cafe protecting most of the organs, except the stomach and intestines which need room to expand when eating. This is a balance of not changing what is successful and being even more successful with some extra protection.
There are also other factors like balancing heat that lead to certain organs being in different places as well.
That makes a lot of sense actually, damn
