IMHO, the most valuable components are the mechanical things, like switches, connectors, and hardware. Resistors and capacitors are a waste of time. Big inductors, like from SMPS, are valuable, if you know what they are. IC's are probably irrelevant. If they are labeled, MCU's are protected and cheap. Other logic chips are also cheap. If they have proprietary labels, forget it. There may be some rare IC's with value. But it is certainly not worth the time to remove most of the IC's, identify them, label them, and catalog.
