For sale 12 Samsung desktop computers used once

The devices are clean and the buyer has the right to inspect and test them. 12 new devices that were used only once for a duty rotation, then remained in their offices and have been well preserved. They were purchased for the Dawah and Guidance office in Al-Badi'ah and stored in closed, secure offices. I don't know their specifications or any details, only the information shown in the advertisement.
