It is an external PCIe connection. You run a cable to a compatible eGPU dock and attach a desktop graphics card, which the K12 then uses for gaming or GPU work.

How many drives can I install?

There are three M.2 2280 slots, all PCIe 4.0. That lets you run several fast NVMe drives without an external enclosure.

Does it have a graphics card inside?

No. It relies on integrated Radeon graphics, so serious gaming needs an external GPU over OCulink.

Is it good for a NAS or home lab?

Yes. Dual 2.5G LAN, Wi-Fi 6E and multiple NVMe slots suit virtual machines, media servers and fast local storage.

What comes in the box?

The mini PC itself with its power adapter. An OCulink cable, eGPU dock and graphics card are separate purchases.

Can I upgrade the memory and storage later?

Yes. Storage is user-accessible through the M.2 slots, and memory can be swapped, though you should confirm the exact memory type for your configuration.

Our take on the GMKtec K12 Gaming Mini PC

The GMKtec K12 is a small-form-factor desktop built around an AMD Ryzen processor with an OCulink port for an external graphics card, three M.2 2280 PCIe 4.0 slots, dual 2.5G Ethernet and Wi-Fi 6E. The OCulink connector is the standout: it lets you add a desktop GPU for gaming without buying a full tower, and the triple M.2 slots give unusually generous storage expansion for this size. It suits gamers who want a compact base plus an eGPU, and home-lab or NAS-style users who want fast networking and lots of NVMe storage. Against mainstream mini PCs it trades built-in graphics power for expansion; against full desktops it gives up internal GPU space and easy upgradability.
