At this point it seems like you have to make a decision you should have made before you started-do I have custom built cabinets or off-shelf cabinets? If they were custom built then you are in for some work for a DIY person. If they are off-shelf, as you would buy at your local builder supply store, then you should be able to remove just that one section. IMO-usually custom built will not have walls between sections, and off-shelf cabinets will. There's always the possibility that someone, when installing the cabinets, glued the off-shelf units together at the sides, making this difficult. Sit back, relax, think, think again, and re-approach the job. You'll figure this one out. Good Luck, David
