There is a lot of great information here. I have been asked many times if a customer should get plywood or particle board cabinets. I recommend plywood but today particle board is normally made with a far better quality control method and with better resins and glues. These cabinets can last 3o years or more unless you get a flood it should not be a problem using these better engineered woods. Particle board is also referred to as engineered wood in many places.
