The problem of nerve impulse conduction (Score:5, Informative)
In addition to convenience, there's a good reason the brain is located in the head...in close proximity to the major sensory organs (eyes, ears, nose, mouth). This placement minimizes the time lag of neural impulse conduction, by minimizing the necessary length of nerve connecting the sensory organs to the brain. For this reason, I wouldn't expect many species to evolve with a larger-than-necessary distance between their brain and their sensory organs (unless such creature evolved a much faster method of conducting nerve impulses than we possess).From TFA:

Instead, we evolved scarring, which cuts off resources to an area in the hopes that we can still feed ourselves without it. As another benefit, we close off wounds from infection faster than animals with regeneration.
Studies in mice [bbc.co.uk] have shown that shutting off the ability to scar leads to regeneration. The ability lies with in us, but it closed off by the benefits of scarring. Now, under modern societial pressure, we may be better off learning how to suppress scarring since it no longer means an inability to feed ourselves. Some have argued that organ regeneration will be the antibiotics of the 21st century in that it will revolutionize medicine.

The case could be made that the mollusc body plan is the most successful on the planet. Squid, for instance, out-mass pretty much all other animals, in an astonishing variety of ecological niches (okay, not sure about krill... any biologists care to refresh my memory?). Molluscs can be found in just about any part of the earth.
As far as sentience goes, if humans crap out and extinct ourselves, my vote for the next evolutionary chance at the reign of intelligence would be for the cephalopods. They're adaptable, have a proven problem-solving intelligence, are highly communicative in ways we're just beginning to understand, have excellent eyesight, and octopuses in particular are highly dextrous.
Don't underestimate the mighty mollusc.

As others have pointed out, the human brain would make most logical sense in the head. Being near the sensory organs is rather important to ensure fast response to external stimuli. Also, the chest cavity makes for a lousy place for brain storage. I guess the ribs and like could've evolved differently, but it just doesn't seem like an effective barrier. It is also mid-mass so your brain would get bounced around with just normal moving and sleeping. Not really a great idea. At least in the head it is fairly protected from that sort of stress.
The reproductive organs...well I just would not want to think about the trouble this would cause. Our mouths already have a confusing time with the eating and breathing. There are problems with this system mind you. Our bodies don't seem to like the idea of eating and breathing much at the same time. Also, I think I would rather have my less pleasant bodily functions sharing space with my reproductive organs than with place where I eat, drink and breath. Also, reproductive organs would have bad protection in your mouth. Besides the dangers of self mutilation (I mean imagine if this thing bit its own balls), the area is grossly exposed. The mouth is technically an external area that receives a great deal more bacteria then your lower regions.
For any major change to have occured in the evolutionary path, something major would have to happen to the environment. Environment played a huge roll in our evolutionary path, and I would like to think that genetics, natural selection and all that fun stuff worked together to produce the best form possible.

A brain in the chest might have some serious overheating problems on top of the wiring issues mentioned elsewhere. Etc...
Evolution has proven superbly effective at creating workable systems because any component which is serious suboptimal causes the extinction of the entire line that contains it. Nature is extremely wasteful in the trial and error process which is natural selection, but nature is also extremely prolific so those creatures that survive can thrive on the failure of others. No designed organism can compete with an organism that evolved, even if that evolved organism has some defects like vestigial organs or an enhanced tendancy towards cancer in the post reproductive years.
I find this one of the biggest defects in the whole (un)intelligent design argument, what I call (u)ID. Design is not a desirable process, it is actually undesirable. A designed creature is not at all to be considered better or more noble than one that wasn't designed. Quite the opposite, as the preposterous article shows. Designs are oversimplistic, inflexible, assume fixed conditions in the environment, and cannot function beyond their designed requirements specifications. For things as trivially simplistic as watches or cars or air traffic control systems, the process of designing the product may be profitable (though even there it can be difficult or impossible to achieve all goals), but not for something as complex as a living organism.

Suppose I design an evolution process that is effective at creating workable systems, then by your claim, my design (evolution) must be oversimplistic, inflexible, assumes fixed conditions, and cannot function beyond specification. This is a contradiction to your claim, so evolution process must not be effective, or your statement about design is wrong.
Instead of "serious suboptimal causes" you should use the word "defect." Of course, no matter which words you use, your claim is a useless tautology, since a component that extincts is a component that has defect and vice versa.
But if you just say suboptimal, you can easily find someone who is biologically superior than you, then by your claim you should be extinct. But (I hope) this is not the case for you. There is observably some give or take on how suboptimal you can be. However, this implies that evolution is not so effective because it allows suboptimality, therefore a contradiction to your claim.
I hope other scientifically curious people are much more logically rigorous than you when defending evolution.

Namely, the brain in the chest would require a larger chest cavity, thus a larger torso, and more weight. As well, the extra pair of arms would add to this. The heart would likely need to be larger to support the extra mass. Also, I think the brain would not be as free to grow/evolve to larger sizes when surrounded by all this ribcage, heart, lungs.
Instead, I think we could really benefit from the addition of one or two more hearts. Why are all our other organs redundant? (even the brain is a dual organ)
In the area of reproduction, instead of putting genitals in our mouths, take another cue from the bird world... Let's keep our reproduction like it is, but make women lay eggs. If sexual intercourse caused a woman to develop an infant-sized egg that she had to lay three days later, we would probably see a lot fewer teen pregnancies. In addition, a fetus developing in the egg would allow much more flexibility in prenatal care. It would likewise put an immediate end to the abortion issue, as the debate would no longer encompass a woman's right to do as she pleases with her body.
One of the more interesting possibilities in medicine today is that scientists may be able to reactivate the gene responsible for regeneration of organs, so you could re-grow lost kidneys, lungs, even limbs, as we can already regrow liver tissue. That's a wonderful bit of evolution that we lost, I can't possibly imagine why.
