Should/Can I save it?

Hi all! I have an old G4 Laptop (PowerMAC)that I had the hard drive replaced on in 2014. Unfortunately, when I got it back the moment I turned it on, I actually saw smoke and it went off never to come on again. I put it in the closet where it remained until this morning. The problem I have is that it seems a shame to destroy it but I can’t repair the HD myself and I don’t know if I can find someone else to do it. if I give it away to someone, I am worried that my personal information could be retrieved by some computer savvy person. Even fours years ago when it happened it was hard to find a HD for it. I would love your thoughts on whether it might be worth saving for someone or some reason, whether someone can steal the data on it if I give it away or sell it, or whether it might be best to destroy it-which would be really hard as it is still beautiful?
