Uhh, someone fully submersed a pc in oil several years back, built an entire rig out of it, and the fear that stuff would 'fall apart' after a year was just a myth, the pc is well over a year old now, nothing has deteriated, (aside from 1, yes 1 sticker) and it has not crashed once.
Heres some pros besides the thermals.
No dust.
Its a completely enclosed system, nothing enters, nothing leaves.
Because there is no dust,
No static.
Because every component is submerged with a non conductive matieral, no other part can 'arc' with another part. So frying your mother board because a spec of dust got into a component, and caused a static shock, is impossible.
Hell the one I saw, they took the casing off of the power supply, fully submerged the POWER SUPPLY in the Mineral Oil, and it just made it 10x cooler.
Infact, the only thing they found was that creating boubles in the thing, made the temperature go up faster.
About the heat, unless they are using some kind of 'new-gen oil' (like that one that was linked earlier) what basically happens is the temperature through out the pc is the same.
if its 30C at the cpu, its 30c at the video card, and 30 c at the HDDs.
Now, tell me this.
what happens if you have a road, that has 3 different temperatures at 3 different points?
however, it won't stay at a low temperature, it'll just go up much, much slower. (12 hours before it starts to get above the 50c point, but it won't really go that much higher.)
Of course, they also tossed in a Standard cooling pump into the mix, and that just made it even more awesome... Oil submerged + constnatly 20c...
