iCloud/iTunes - PC

Hi All,

I have a desktop PC that I just want to get rid off [I am not selling it].

I have iTunes & iCloud on it but I have not used them on the PC in years.

I suppose what my question is, do I have to log out of iTunes/iCloud on the PC before I destroy the hard drive?

Would there be any ramifications if I do not log out or forgot to before I have destroyed the HD?
