Compact Intel i3-N300 barebone

The KUBB KM-300-16256P-GR is a fanless mini PC measuring 3.15 inches square. It ships with an 8-core Intel Core i3-N300 processor, 16 GB of LPDDR5 memory and a 256 GB M.2 SSD. Windows 11 Pro is pre-installed in a graphite aluminium chassis built in France.

Ideal for silent office and edge deployments

This unit suits buyers who need a compact, passively cooled system for productivity, digital signage or light multitasking. It is not for users who require expandable memory beyond 16 GB, discrete graphics performance or additional 2.5-inch drive bays.

Fixed 16 GB LPDDR5 memory

The board integrates 16 GB of DDR5 4800 memory that cannot be upgraded. This single specification decides whether the platform meets your workload capacity or if you must select a system with SODIMM slots.

Questions about this item

How much heat does the fanless i3-N300 produce when it runs all day?

The i3-N300 is built on an efficient architecture optimised for low power consumption and the aluminium chassis acts as a passive heatsink, so it stays cool without a fan.

What must I already own to start using this barebone?

It ships with 16 GB DDR5 and a 256 GB SSD installed, so only a monitor, keyboard and mouse are needed.

Will my older 1080p monitor work with the HDMI 2 outputs?

Yes, the Intel UHD Graphics drives two HDMI ports that are backward compatible with 1080p displays.
