Hmmm.... No idea what a powerboard is. Internet searching hasn't been much help either. Are you asking about an exercise machine, strip of electrical outlets, something to do with a computer's inner workings, or none of the above?
To answer as best I can: No, I don't have exercise machines. Yes, I periodically dust my power strips, and no, I no longer crack my computer cases to dust their interiors.
Like me, at some point you've done physical repairs to a computer or laptop.
