Essential NUC 14 barebone

The ASUS RNUC14MNK2500000 is a compact barebone mini PC built around the Intel Processor N250 with integrated Intel UHD graphics. It targets system builders who want a small footprint for office work, digital signage or home-lab duties and prefer to choose their own memory and storage. The chassis includes a VESA mount for behind-monitor installation.

Single SO-DIMM DDR5-4800 slot

Memory expansion is limited to one 262-pin SO-DIMM slot supporting DDR5-4800 up to 16 GB in single-channel mode. No memory is installed, so the buyer must supply a compatible module; dual-channel operation is not possible and the 16 GB ceiling is fixed by the single-slot design.

Triple display outputs and 2.5 GbE LAN

Video outputs comprise DisplayPort 1.4, HDMI and USB Type-C, each capable of 4096×2160 at 60 Hz, enabling three simultaneous screens. Networking uses a Realtek 2.5 GbE controller alongside Wi-Fi 6E AX211 and Bluetooth 5.3. Storage relies on a single M.2 2280/2242 slot accepting PCIe 3.0 x4 NVMe or SATA drives from 128 GB to 4 TB.
