The mini PC market just got a lot more interesting for budget-conscious builders and tinkers. After its initial debut in China earlier this month, the GMKtec NucBox K15 has now launched worldwide, and it’s bringing a feature rarely seen at this price point: true external GPU (eGPU) support. Starting at just $359.99, this compact machine is positioning itself as a versatile hub for work, media, and—with the right accessory—surprisingly capable gaming.
The eGPU Edge: OCuLink Takes Center Stage
What truly sets the K15 apart in the crowded budget mini PC space is its dedicated OCuLink port. For enthusiasts, this is a big deal. OCuLink provides a direct, high-bandwidth connection to an external graphics dock, often with less overhead than standard Thunderbolt solutions. This means users can effectively bypass the integrated graphics and connect a desktop-class GPU, transforming the humble K15 into a legitimate gaming or creative workstation.
But GMKtec hasn't put all its eggs in one basket. The mini PC also includes a USB4 port, which is compatible with the more widespread Thunderbolt-based eGPU enclosures. This dual-approach future-proofs the device and gives users flexibility based on their existing gear or preference.
Under the Hood: Meteor Lake on a Budget
Powering the system is Intel’s Core Ultra 5 125U processor from the Meteor Lake generation. In our time with the device, the CPU proved itself as a capable performer for everyday productivity, multitasking, and media consumption. Its integrated graphics, however, confirm this isn’t a standalone gaming box. You’ll struggle to hit playable frame rates in modern titles at 1080p on the iGPU alone—which makes that eGPU support all the more critical for gamers.
Where the K15 shines is in its upgradeability. It offers a trio of PCIe 3.0 slots for NVMe storage, supporting up to a massive 24TB total. For memory, two SO-DIMM slots can accommodate up to 96GB of DDR5 RAM, ensuring the system won’t bottleneck your ambitions.

Ports and Connectivity: Surprisingly Robust
The connectivity suite is generous for a device in this class:
- Video Out: 1x HDMI 2.1, 1x DisplayPort 1.4
- High-Speed Data: 3x USB 3.2 Gen 2 Type-A, 1x USB 3.2 Gen 2 Type-C
- Legacy & Audio: 2x USB 2.0, 2x 3.5mm audio combo jacks
- Networking: 2x 2.5G Ethernet ports—a boon for network storage or network-intensive tasks.
- Wireless: Wi-Fi 6E and Bluetooth 5.2 round out the package.
Cooling is handled by a two-fan system, which preliminary reports suggest does a decent job of keeping the Meteor Lake chip thermally in check without excessive noise.
Pricing and Configurations: Three Tiers to Choose From
That enticing $359.99 starting price is for a barebones kit (no RAM or storage). For users who want a ready-to-go system, GMKtec offers two pre-configured models:
- $579.99: Equipped with 16GB of RAM and a 1TB SSD.
- $699.99: Upgraded to 32GB of RAM and a 1TB SSD.
For those opting for the barebones route and looking for top-tier storage, a drive like the 2TB Samsung 990 Pro (currently $254.99 on Amazon) would be a perfect performance match for the K15's capabilities.
Final Thoughts: A Niche, Powerfully Filled
The GMKtec NucBox K15 isn't trying to be everything to everyone. Instead, it carves out a smart niche: it’s an affordable, well-connected desktop base for everyday computing that holds the door wide open for a massive graphics upgrade. For the user who wants a small, efficient daily driver but dreams of weekend gaming sessions with a powerful eGPU, the K15 presents a uniquely cost-effective path to get there. Its global availability now makes that path accessible to far more users.
