Q: The Packard bell PC is a iMedia 1516 and is 3 yrs old. can i use the parts of it i.e. Hard Drive, RAM, PCI Cards, DVD Drive, Processor etc in a Dell XPS 420
A: It depends on the parts you want to swap. In most cases, yes, they are interchangable if both computers uses the same specs. For example, RAM - If both motherboards use 168-pin 400Hz RAM cards, then you can swap them. PCI Cards - All PCI cards you can swap to another motherboard that has a PCI slot Hard Drive - You can swap hard drives if both motherboards use the same hard drive slot (IDE or SATA). But you will have to reformat the hard drive. Processors - if both computers have the same socket and the new motherboards supports the processor, then yes.
