Hummmm interesting question...
we have not seen a masked S5 yet

any pictures?
Does anyone use a dust filter on their s5? I have one on the push fan. It contributes a bit to the noise but what do you all do with dust?

Seems like it does a decent job. But really, how do you guys deal with dust? do you clean the miners out once a month or some other schedule? Doesn't dust contribute to increased heat?
