ASRock Industrial NUCS Ultra 300 BOX Series Intel Core Ultra Series 3 Slim NUC Mini PCs with Wi-Fi 7 and USB4

Behind a signage screen or inside a self-service kiosk, the space for a computer is often decided long before anyone chooses one. The ASRock Industrial NUCS Ultra 300 BOX series is built for that situation: slim NUC mini PCs on Intel Core Ultra Series 3 (Panther Lake-H) processors that mount on a VESA bracket and still drive four displays, with Wi-Fi 7 fitted and a built-in NPU for local AI work.

Every NUCS Ultra 300 BOX model shares the same design. Two SO-DIMM sockets take DDR5 up to 128 GB, and every processor option supports In-Band ECC. Storage sits on two M.2 M key sockets, one on x4 PCIe Gen5 and one on x4 PCIe Gen4, with Intel VMD RAID 0/1 for mirrored or striped NVMe. The front panel carries a USB4/Thunderbolt 4 port with DisplayPort 2.1, a USB-C port with DisplayPort 1.4a, two USB 3.2 Gen2 Type-A ports and an audio jack; the rear adds two HDMI 2.1 outputs up to 8K, two more USB 3.2 Gen2 Type-A ports and an Intel I226LM 2.5GbE port. A Wi-Fi 7 and Bluetooth 6.0 module ships on the M.2 E key socket, and security uses firmware TPM (Intel PTT).

The range splits by processor. The NUCS BOX-358H carries the Core Ultra X7 358H, a 16-core processor with Intel Arc B390 graphics and DDR5 7200, for signage and edge AI work where the graphics load is heaviest. The NUCS BOX-325 uses the eight-core Core Ultra 5 325 with Intel Graphics (Xe3) and DDR5 6400, which suits kiosks and automation terminals with lighter processing needs. Both share the same I/O, cooling and power design, so a project can move between them without redesigning the installation.

In practice the NUCS Ultra 300 BOX series suits retail and kiosk, digital signage, automation, robotics, entertainment, security and edge AI installs. Both models run from 12 to 24 V DC through a barrel jack, ship with a 19 V 120 W adapter and VESA bracket, operate from 0 °C to 40 °C with a fan, and carry CE and FCC marks. ASRock Industrial supports Windows 11 and Linux on these slim NUC mini PCs, and a watchdog timer helps unattended units recover.
