Since the top of the case is an exhaust, we normally do not see a benefit to filter it. All it would do is prevent hot air from exiting in the case. But in this situation it was an easily removable piece that most users can make the determination on. If a customer with a graphite grey 500R would like that piece for filtering, we'll be happy to provide it. But like I said, it's pretty much cosmetic up there only, and as for dust filtering, most people don't use the top as an intake.
What should I do in order to get that piece? Any dust filtering is better than none, and I always have one intake up top to supply the CPU heatsink with fresh air.
I can probably make some kind of filter myself but I will always prefer non-ghetto-rigged solutions. Either way I'm glad my case came complete after all
