The other side of the wall cabinets in the kitchen was a little more work because it's constrained not just by the wall, but by the door opening too.
After realizing that it was going to be a pain to put the old exhaust fan back up, we decided to buy a new over oven microwave. This required wiring a new outlet as well since the old fan was hard-wired in.
Everything managed to fit together as planned. The only thing i have left to do is connect the duct work from the microwave to the exhaust duct.
