The hard disk stores all the system data as well as your personal data. A hard disk of 100 GB can be regarded as a minimum. Its size is dependent on how many photos, music and movies you plan to store on your system. You can go for a 160GB or 250GB hard disk in case you need to store lot of data, though 120 GB is generally more than enough.
