A very fast reliable P4, upgraded memory to 512MB, 80GB hard drive. The following is already installed on the system: Windows XP Pro with SP3 and the latest updates, AVG antivirus with the latest definitions, open office. This is a very clean unit and it is expandable. The deal is with the power cord. Please let me know if you have any questions.
