GMKtec NucBox K10 (Core i9-13900HK)
The NucBox K10 is a larger mini PC (188.6 x 178 x 38.9 mm) with Intel's Core i9-13900HK, a 14-core, 20-thread Raptor Lake chip that boosts to 5.4 GHz. Its standout feature is storage: three M.2 2280 NVMe slots, unusual at this size, which makes it attractive as a compact NAS or a VM host with lots of fast storage. It takes two DDR5 SO-DIMMs up to 96 GB and is cooled by a dual-fan, dual-heat-pipe system. Networking is a single Realtek 2.5 GbE port. It has no USB4 or Thunderbolt: its Type-C port is USB 3.2 Gen 2 (10 Gbps) with DisplayPort output. Display outputs are 2x HDMI 2.0 and 1x DisplayPort 1.4, with Iris Xe graphics.

Check before you buy
- There is no USB4 or Thunderbolt port, so an eGPU or Thunderbolt dock will not run at full speed.
- There is only one Ethernet port (Realtek RTL8125BG). For a router or a dual-NIC Proxmox setup, add a USB NIC or pick a dual-LAN model.
- Check how many of the three M.2 slots are filled and that the drives are NVMe.
- Confirm the 120 W 19 V adapter is included; the 13900HK draws a lot of power under load.
General off-lease checks (BIOS passwords, Computrace, missing drive caddies) are in the used mini PC buying checklist.
