There's a sale on external hard drives at a store. The prices are really good, and the prices on internal hard drives are much higher. Would it be possible to crack open an external hard drive and use the drive from inside in a NAS? I don't know if there's anything different about the drives used in external hard drives that would make it incompatible, just want to make sure it'll work before spending the $$. I know it'll void the warranty by opening up the enclosure.
