Is there any true dust free case out there?

[Guest Gabbs]

So I see tons of cases with meshes, filters for the coolers, etc., but there are still a lot of openings, holes, slots and whatnot that still let dust in.

Is there anything out there that comes dust free? Or the only way is to DIY?

Thanks.

not possible

There's really no way to completely dust proof a case short of vacuum-sealing it.

that's impossible

how do you imagine the air to get inside then?

i have filters on all my intake fans and things get dusty in 3-4 months

Its impossible, unless your case is inside of a vaccum lol.

by the nature of airflow, dust free is impossible unless you are working in a dust-free environment. You can reduce the amount of dust in a case by how you set up your air pressures. A positive air pressure in a case (more fans blowing in than out) will reduce the amount of dust gathering there.

I was hoping someone made a stealed case with filters on the fans in order to limit the amount of dust that goes in.

All I see are cases with openings all over them.

If you want as little dust as possible have positive airflow and have a look at that mammoth case thingy from Silverstone.

Is positive airflow as effective as having the same in and out airflow?

Yeah I think this has been pretty much covered off but I'll add my comments too

 

Truly dust free is impossible, but you should be able to get close enough for all practical purposes by ensuring a positive pressure setup and having very good (fine) filters on your intakes.

more so.  Consider if the pressure in your case is always higher than the room around, no air (and no dust) will enter except through where it is being drawn in (the filtered intakes).

 

If you have net 0 or worse yet negative pressure, air and dust will seep in through every tiny hole

mineral oil build.

Positive airflow is more effective than having the same in and out. Also, really have a look at that case I said about, uses HEPA filters or whatever and look quite robust

In theory, you've actually got a good point here

 

In practice though, I have to imagine a few things would be problematic:

• First of all, maintaining a system like that is a lot more hassle than just blowing dust out from time to time, so probably not worth it
• Unless the system itself is sealed such that the only material that can enter or leave is the fluid in the liquid cooling loop, dust could still settle on the surface of the oil and eventually get mixed in an suspended in the liquid.
• The fans/rads and all external components would still get dusty

I'm looking at a review of that case right now. That thing truly is a mammoth

I don't know of any dustfree cases other than a few passively cooled ones that can be silicone-sealed. But there are enclosures where you can put the computer that keep it amazingly clean. They're really expensive and meant to be used in factories and facilities with a lot of dust and other particles in the air.

 

This barely relates but I once repaired a laptop in a bakery. It was friggin' filled with sugar powder. We got them a new laptop and installed it in a filtered and sealed workstation stand. The 32-bit Vista machine ended up costing them around 7000€

you want more in than out. That reduces dust build up. Also, try and keep your case on a desk, not on the floor or near to it.

For science's sake I have to clarify something.  You are not setting it up to have more air flowing in than is leaving.  That would cause more and more air to build up in the case until it exploded.  What you are doing is having it setup so there are more fans (or more "fan power") pulling air in than there are blowing it out.  That will cause (only at first) more air to enter than is leaving, but it will quickly reach equilibrium due to the now higher pressure in the case (what you want) causing air to exit through the exhaust fans and other holes at the same rate it is being pulled in at.
