How do you remove dust from a new iMac 27"

[matabot]

How is it done? I have a heavy workload, and don't want it to have issues with overheating etc a year or two down the line. How is dust removed? It's not like the last generation where the screen can be pulled off with suction cups? Is there a filter on the bottom intake or something?

No filter. Wish I had something on my old one when it was a cheese grader/dust collector and worked it's way into the screen. The new ones shouldn't have a screen dust problem, but the board will eventually get some.

Since the air passes by the Ram, you could pull a stick every so often and wipe it with your finger to check the progress, or wipe into one of the intake openings with a moist white cloth to check it that way.

Design a very tiny strip of light density foam (designed for filtering air) and attach it to the bottom was a thought, but if you restrict the airflow by more than a tiny bit, you might cause fan problems. They run at low speed all the time.
