One additional question I would have - what is the purpose of the green spring loaded button right underneath the optical bay area and right above the topmost 3.5" HDD mount? Any ideas?
To answer my own question - at least from what I managed to find out, this is a quick release switch for a slim CD/ DVD drive that one can install just above the topmost 3.5" HDD drive.
So in theory installing this DVD drive one could still have three 5.25" bays free (or two, if you have the carry handle in the top bay).
