This is a fully functional computer with hard drive. Includes an apple mouse and keyboard as well as an iSight camera. Specs: https://everymac.com/systems/apple/powermac_g5/specs/powermac_g5_2.0_dp.html It has 512 MB of RAM. Apple no longer supports this hardware so the OS and software cannot be updated. I have left a version MS Word installed as well as a few other apps.
