Like this one. The guy got what looks like a tank + pc case combo and filled it with mineral oil, then hooked a radiator up to it with a pump, case fans, ect. Is that practical? Because it looks like it would be a LOT of fun to do.
Depends on what you mean by 'practical'? Is it worth doing?
Well, if you're an extreme overclocker, maybe. It certainly seems easier than dealing with peltiers or liquid cooling heatsinks and pipes. Just get a tank, a pump, and a radiator, along with a bunch of mineral oil, and you're good to go.
If you don't plan on changing things very often, its definitely easier to clean, especially since there's no real dust to speak of.
Cost wise? Well, see the parts you'd need above. Comparable to what you'd need to do liquid cooling anyway.
Necessary? Not for a standard desktop. If you want it for the 'hey check this out factor'? Sure!
I was looking at these the other night after getting prompted by one of my BL2 buddies... I love the idea, because I'm sure it can keep extreme OCd systems pretty cool, but... if you've ever owned any kind of aquarium or fishtank you know how much of PITA it is when you have to drain it and fix/change something.

On the youtube videos I was watching, one of the engineers who started doing this stated that it takes a week (at least) for the motherboard to dry off when you pull it out. So if you ever have to service it, you'd be without your machine for at least a week.
But... if you consider all those discussions we were having about chipsets that are soldered to the motherboard, this be an ideal solution for overclocking one those. -- Support Bacteria -- It's the Only Culture Some People Have
