Apparently all microwaves over-the-range can suck in the air at their
bottom, and have an air duct connector at the top, so I won't need a
separate range hood.
The only problem is that they do not sell a range amd a m/w as a single
piece now, so the m/w will have to be hunging off the wall and off the
cabinet above. M/w over-the-range tend to be heavy (> 60 lbs), and I am
a bit worried that the wall may not be able to hold it.
