PC Serial # MXF72203G2 labeled on tower bottom.  Has a Windows Vista product key # sticker on side, though the computer has been wiped and loaded with an unactivated copy of Windows XP.  BIOS photos for verification.  Unit sold AS-IS.

NOTE:  the optical drive needs replacing!  The button controlling disk bay opening / closing no longer functions and you must repeatedly fight with it using an unfolded paperclip in the manual release hole.  It will read CDs once loaded in the drive, though getting them in or out is a major frustration.

Includes original HP keyboard, mouse, and power cable.  All three work as intended.  Photos are of the exact items you will receive.  

Will box and package carefully for shipment.  Ships within USA ONLY via FedEx or UPS.  Questions welcome.  Thanks for browsing!
