[SOLVED] Is this dust accumulation normal on the front of my case?

Quite normal.
That is the intake fan filter which keeps larger dust particles out of the case.
I have 4 dogs and 3 cats in my home. So my computers look like that in about a month. Plus mine run folding 24/7/365 , which means it happens faster than it would with occasional use.

Most of what you see as dust is actually dead skin cells from you and your pets.
