How do you guys keep your Synology Dust free?

Hey guys just wondering how you keep your Synology clean and dust free. I have mine placed in my living room and need to dust it or vaccum it once a while.

I usually Turn it off completely, remove the HDD's and gently dust and then wipe it off with dry cloth. I then vaccum the NAS device, or blow using a Hair Dryer occasionally.

Not sure if this is all safe. I really do not wish to having it cleaned every few days.

Is there a way to create a dust free chamber, not sure how this will impact the heating and cooling or would you rather just cover it by placing a small cloth over it except the back where the fan is.

Would be great to hewr your thoughts and methods.
