Ultra-compact fanless mini PC

The KUBB KM-300-16256P-BL is a 3.15 inch barebone system built around an Intel Core i3-N300 processor with eight cores and a 3.8 GHz turbo frequency. It ships with 16 GB of LPDDR5 memory and a 256 GB M.2 SSD, running Windows 11 Pro from the aluminium chassis. Fanless cooling keeps operation silent in offices, digital-signage setups or home labs.

Suited for silent desk deployments

This unit fits users who need a ready-to-run mini PC with dual HDMI outputs, Gigabit Ethernet, Wi-Fi 6 and Bluetooth 5.2 for peripheral connectivity. Buyers who require additional internal storage bays, discrete graphics performance or user-upgradeable memory beyond the soldered 16 GB limit should consider alternative form factors.

Fixed 16 GB LPDDR5 capacity decides fit

Memory is soldered at 16 GB with no expansion slots, so the configuration you receive is the final capacity for the life of the device. Verify that your workload fits within this ceiling before ordering.

Questions about this item

What external display and input devices do I need to start using the KM-300-16256P-BL?

Connect a monitor to one of the two HDMI ports and plug a keyboard and mouse into the two front USB ports; the unit ships with Windows 11 Pro already installed.

Will my existing 1 Gbit Ethernet switch work with the Realtek RTL8111H LAN port?

Yes — the RJ45 port negotiates 10, 100 or 1000 Mbit/s, so any standard Gigabit switch connects at full speed.

How can I confirm the Intel Core i3-N300 is running at its 3.8 GHz turbo frequency after setup?

Open Task Manager in Windows 11 Pro, select the Performance tab and watch the CPU clock speed rise to 3.8 GHz under load.
