GMKtec NucBox K9: Specs
GMKtec NucBox K9: Design
There's no doubting the stylish aesthetics of the K9, which are identical to the K8. However, it suffers from the same design issues highlighted in the K8 review. While the design is pleasing, for a machine of this price, a higher specification metal casing would be expected rather than the metallic-finished plastic used. Nevertheless, the overall look and feel are pleasing, albeit slightly cheaper than some competitor models. The big difference between the two machines is the switch from the AMD chipset to Intel.
Access to the inner hardware is relatively straightforward. No tools are required to pry off the top plate, revealing the small cooling fan. The fan plate itself is held in place by four small screws. A slight skirmish is needed to lift this plate away, and the mainboard connector to the fan needs to be unplugged before clear access to the internal components can be properly reached.
Inside, the layout is spacious and neat, allowing plenty of airflow through the system with the two large grilled vents on either side. On one side are the two PCIe 4.0 M.2 slots and SODIMM DDR5 memory slots, which in our review sample featured two 16GB Crucial DDR5 5600 modules, giving a total of 32GB, upgradeable to 96GB—one of the largest capacities of any Mini PC. Opposite the RAM slots are the Dual M.2 slots, with one filled with a 1TB M.2 2280 PCIe 4.0 SSD, expandable to two 2TB modules. Under the RAM is the WiFi 6 (2.4GHz/5.0GHz) and Bluetooth 5.2 card, offering upgrade options for future compatibility.

The usual array of ports is on the front and back of the machine. In a slightly odd move, the USB4 port is solely on the front alongside two USB 3.2 Gen 2 and a standard 3.5mm audio port. At the back are a DP v1.4 (4K@144Hz), HDMI 2.0 (4K@60Hz), two USB 3.2 Gen 2 (10Gbps), two RJ45 LAN (2.5Gbps), a Kensington lock, and the DC power socket.
The overall design is neat, but it does feel like the power of the chipset and potential of the machine are slightly underplayed, with only a single USB4 port on the front and a less-than-refined route into the machine for upgrades.
