GMK NucBox K15 goes global as affordable mini PC with OCuLink and 24 TB storage support

The NucBox K15 was initially introduced earlier in December 2025 in China, and now, the affordable mini PC has made a global debut. With the launch price tag starting at $359.99, it stands as a capable system that features proper eGPU support.

To be specific, the GMK K15 has an OCuLink port, making it possible to pair a high-performance eGPU with the mini PC. There's one USB4 port available as well, which further expands the external GPU compatibility.

Under the hood, the NucBox K15 packs the Intel Core Ultra 5 125U, a lower mid-range APU from the Meteor Lake lineup. It features a 4-core iGPU, which we found to be incapable of offering a playable gaming experience at the 1080p resolution, but the CPU performance is decent.

Users can pair this Meteor Lake processor with up to 24 TB of NVMe storage through the three PCIe 3.0 slots (2 TB Samsung SSD 9100 Pro curr. $254.99 on Amazon). There are two SO-DIMM slots, which can hold up to 96 GB of DDR5 RAM. The port configuration is decent as well, and besides the OCuLink and USB4 ports, the NucBox K15 has the following:

• 2x USB 2.0
• 1x DisplayPort 1.4
• 1x HDMI 2.1
• 3x USB 3.2 Gen 2 Type-A
• 1x USB 3.2 Gen 2 Type-C
• 2x 3.5 mm audio combo
• 2x 2.5G Ethernet

Other highlights of this affordable mini PC included WiFi 6E, Bluetooth 5.2, and a two-fan cooling setup. It's worth noting that the starting price tag is for the GMK K15 in its barebones configuration. There are two more options available:

• $579.99 for the configuration with 16 GB of RAM and 1 TB SSD
• $699.99 for the configuration with 32 GB of RAM and 1 TB SSD
