Want a super-quiet computer? Sink it in a vat of mineral oil

OK now here’s a wild post if there ever was one. I found about this guy that submerged his entire motherboard, complete with Fan, in an aquarium filled with mineral oil.

What an experiment! Looks like everything but the drives and power supply are in the tank.

Now, why would someone want to do that? Simple: zero noise and no problems with heat.
