If you go into Accounts prefpane in the System Preferences and delete an account from there, it will give you three options.

1. Save the home folder in a disk image. (Self explanatory)

2. Don't change the home folder. (The account is deleted, but the Home folder stays untouched for you to delete at a later time if you want)

3. Delete the Home folder. (Deletes the account and the Home folder)
