So, I recently got a brand new L2015 27" iMac. Love it so far, the display is beyond incredible. Makes my cinema display next to it look like butt cheese I reside in a smoke free home, have my studio setup in the basement. I notice a fair amount of dust seems to collect on the surfaces of things down here, I tend to have to clean my desk at least weekly. I'm a bit worried about dust collection inside my new mac. Is there any precautions I should take? Back in the day I would periodically crack open my 09 27" and dust it out, also did fairly regular clean outs of my Mac Pro tower. Not being able to get inside this beast has me a bit worried.
