The Dell Precision Tower 3620 is a powerful workstation with plenty of USB ports and a DVD drive. - Model: Precision Tower 3620 - Brand: Dell - Type: Workstation Working condition Xeon1225v5 Memory 8GB, 2 slots available OS Windows 10 Pro Windows 11 certified, but not recommended. Wired LAN Storage is not included, please prepare your own. ○ Includes a third-party power supply conversion cable. Changing the power supply increases the graphics card options. The CPU has been upgraded from 1220v5 to 1225v5, so video output is possible (I think other CPUs can also be swapped). Please note that one of the storage mounting components is not original. CPU thermal paste will be reapplied before shipping. Thank you for viewing.
