How to protect the system unit from dust?

open the side cover, pick up a brush and compressed air, clean everything from dust, repeat every couple of months

Answer 2

Turn off all the coolers in the system unit and cover it with a canvas cover

Answer 3

Well, or as an option, work as a spherical horse in a vacuum.

Answer 4

We put a white lace cover on top, cover the ventilation holes with a thin layer of gauze. Also white.

Answer 5

to create excess pressure inside the system unit, to do this, close all the slots to the maximum, organize the supply of filtered air,
I figured out several stages of purification, sections from a plumbing pipe, a cooler from an exhaust hood, a gauze pre-filter, then FFP2-3 from masks, but laziness, all the problem is how to dock it with the system unit

Answer 6

Air inlet from the front, outlet - from the back through the PSU or even a hull blower. But there is only one input, and the performance of the fan at the input needs to be done a little more than the total for the output. Well, the filter at the entrance. I have been doing this for many years, for a year there is very little dust inside, but the filters have to be changed every 2-3 years, because they simply turn into dust. Server rooms (from industrial buildings) serve longer, but they still need to be found.
