This Apple PowerPC G3 is mainly for getting parts. If you want to use the parts, first, make sure you have basic knowledge of computer hardware. When taking out parts, gently disconnect cables and screws. Be careful not to damage the small components. As for maintenance, keep the parts in a dry and dust - free place. If you're storing them for a long time, put them in anti - static bags. Remember, this computer doesn't work, so don't expect to use it as a whole. Always wear anti - static gloves when handling the internal parts to avoid static damage.
