i was just looking at this case
and noticed that it had washable filters. I can see where this might be of value, especially in a dusty environment. But what happens when it gets really dirty, does it warn you like a projector or window air conditioner that you need to clean or change it? Or does it just shut down?
I do like the doors over the optical drives. that too would help keep some dust out of the case. Or at least it seems like it would. I am trying to find the right setup for a manufacturing office that wants some new computers. they are in an office but the office gets pretty dusty too.
