  There are peltier junction heat sinks available now and you are
right the little suckers draw quite a bit of current. They also
have this nasty habit of producing a cold surface on one side and
a hot surface on the other. You may be cooling the CPU but you are
also pumping a lot of heat into the computer enclosure itself
multiplying your heat dissipation problems.
 Personaly and from experience with cooling industrial power supply
diodes and power transistors I would attack it with large amounts of
aluminium and a dedicated high velocity fan before I would go with
the liquid cooling option.
  The majority of the little cooling fans they place on CPU's
are no more effective that a moth hired to flap it's wings over
the thing. There simply is not enough airflow to dissipate any
appreciable amount of heat. The type they use inside of the power
supply however is about the right size. If mounted with it's air
flow passing over a considerable amount of cooling surface, in
the form of a heat sink, it should easily keep up with your wildest
over clocking experiments.
  Just be sure to use the proper methods of attaching a heat sink to
a CPU's surface to maximize it's performance. IF you can't get your
hands on thermaly conductive adhesive you should at least be able to
find some thermal heat sink grease for the job. If you can't find the
thermal grease at a local electronics parts store you can get it in
small tubes at an auto parts store. They sell it for treating the
mating surfaces of electronic ignition modules to the side of the
distributor housing.

  I agree with you on that one. While the mother board would probably
survive a couple assults like that hard drives, CD drives, DVD and Zip
dirves, and your power supplies are much less forgiving in that respect
and don't react kindly to high moisture bearing materials like water.
