This is a used Epson all-in-one PC. The HDD has been replaced with a 500GB SSD, and the memory has been upgraded to 16GB (photos 4-6). It has a built-in DVD drive. The OS has been updated to Windows 10 Home. The items for sale are the main unit, the original keyboard, mouse, and AC adapter. It's an unusual desktop PC that has a detachable battery and can continue to run during a power outage, but since it's an old model, please consider the battery as a bonus. There were no issues during the initialization process. While there is some aging of the exterior parts, there are no cracks.
