This is the Beelink mini PC EQ12. The specifications are as follows: OS: Windows 11 Pro OEM_DM *Windows license is included with the unit. CPU: Intel Alder Lake-N100 Memory: DDR5 16GB Storage: NVMe SSD 500GB Network: 2.5 Gigabit Ethernet x2 Wireless LAN: Wi-Fi 6 (802.11ax) I haven't replaced or added any parts, so it's as per the official specifications. I think it's a quiet, compact, and energy-efficient product. I confirmed that it was working without any problems just before. I performed a "reset" from Windows 11 recovery. Drivers can be obtained from the manufacturer's page: https://dr.bee-link.cn/ as needed. The condition is clean, but it is a used item, so please understand this before purchasing.
