IT lads use a wrist band that earths them and prevents any static build up while they have thier hands in the gubbins.
You can also regularly touch something with a good earth like a radiator but the straps are easy and cheap.
I have also noticed a more substantial build up on fan blade surfaces in the past and I have removed them and washed then in warm soapy water. Depends on air quality and how easy it is to get to.
Frequency is so much dependant on air quality but I would suggest that if you havent had a look in over a year it is time for a peek. If everything looks fine stick it back together and leave it longer next time. If everything is covered with dust give it a once over and do it a bit sooner next time.
In poor quality air situations it may be worth using an additional filter over the intakes which can be removed and washed regularly, assuming it is round the back and out of sight. The best material for this is the green kitchen scourer pads that can be held over the grid with some cable ties and of course wash easily. This will extend your requirements to open up the case dramatically.
