I've done this in the past - you don't have to use updated machines (or even functional ones), to go through things like laptop, printer, or PC tear down activities. For some students, this may even be a bonus because of the fear of "messing something up" as a result of learning how to do proper system tear downs. Or even if the machine is working, if it's a $50 machine that gets popped in the lab, well, no harm done.
