Has anyone done a completely sealed case??
I mean, why are we sucking in dust when we can send the cooling component outside the case?
 
Solution
I can assure you that you will still have to go in the main case at least semi annually and clean out dust. Dust doesn't get produced because of fans heck dust isn't even dirt for that matter. Dust consist of dead skin, insect corpses, etc. Trust and believe if you never open the case you can find bugs in there over time. Their hard shelled bodies will eventually turn to dust which will then still create heat over time.

Dust if dry and easily flammable I would not assume that an external liquid cooling system will completely solve a dust problem. Remember the human body loses roughly 10,000 skin cells daily (thats just skin, not including the 100-150 hairs that fall off too), also dust seems to find its way into anything. Main reason...
Why would you? Sure you can have a radiator outside the case, but its more prone to leads and damage, and it will still collect dust. There are other components that generate heat as well. HDDs, PSU, motherboard vrms, and a few others generate heat that needs at least some sort of cooling.

The idea is to bring in cool air with intake fans and extricate warmer air through the exhaust fans. There are devices that are sealed (ie. tablets and maybe ultrabooks). These happen to be less powerful and do not generate as much heat.

But do it brah, good luck. I hate fans...they are stupid.

Yea, but it's easier to clean the radiator. You can connect all the heat parts to the external radiator.

It would be quite impractical to "connect all the heat parts to ..." The large heat generators include the CPU, all RAM modules, the GPU, the Northbridge and Southbridge chips, the audio chip, the bus controllers, the resistors and capacitors of the mobo's Voltage Regulator circuitry, the HDD's, the optical drive, etc. NONE of these is made in any "standard" physical form so that you could design a "standard" type of heatsink for each type, fasten it on, and then connect to an enormous network of tubing - either solid metal heatpipes or liquid-flow tubing - to move the heat outside. A more practical solution might be to design like a household air conditioner (but excluding the compressor system). Install one or more large heat exchangers inside a sealed case, plus several fans to move air around rapidly so that air can carry heat from generator elements to the heat exchanger. Use a liquid loop to pump the heated liquid outside to another heat exchanger with its own fans to blow cooler outside air through the exterior exchanger.

Sounds expensive and complicated to me, with a higher active component count leading to higher probability of failure.

Remember the human body loses roughly 10,000 skin cells daily (thats just skin, not including the 100-150 hairs that fall off too), also dust seems to find its way into anything. Main reason say you build it and seal it tight. What of the thousands of skin cells (microscopic) left from your skin inside that sealed case? Now in just a couple days that turns to little clumps of dust.

However, building an external LC should reduce the amount significantly so maybe you might get away with cleaning the case out once a year! I would say try it out if you're adamant about reducing dust in a case and see where that takes ya! Then let us know your results after several months, open the case and see how much dust was there. Whether you would consider it negligable or not! Anyhow hope it all works out the way you plan.
