I do not have a MBP 2016, so I can not dismount, but the image I see a grid behind the speaker placement ... but mostly I read reviews that give the acoustics of these models as "better" and not " worst "of the past and those directly comparable as encumbrances.

(I apologize for English Google ...)

"... Most of the grille doesn't include full through-holes, prompting us to question why the dimples, Apple? ..."

Try to inform you what the BASS REFLEX is ... and you'll find the answer.

The air mover "behind" the membranes for the creation of the sound is as important as the moving air "before" to the membranes.

 A simple picture may be enough to understand what "might be superfluous" that the grid holes are in front of the speaker membranes:

I still have the curiosity to know who manufactures the display.

Someone found the label of the manufacturer?

I apologize for the reply after over a year.

No iMac 24 "both 2007 and 2008 can accommodate a SATA Superdrive. This is certain.

It is clear that this installation is made to the adapter referred to as "Related Products": http://www.ifixit.com/Apple-Parts/12-7-m....

So any HDD or SSD you enter this run at high speed to 100 MB / sec of UltraATA100.
