At the heart of this system is Intel’s formidable Core Ultra X7 358H processor, paired with capable Arc B390 graphics. This pairing is engineered to deliver exceptional performance, effortlessly handling demanding office applications and providing genuinely capable 1080p gaming experiences right out of the box. It’s the perfect marriage of power and portability.

What makes the NUC BOX-358H truly compelling is its design philosophy: it offers serious performance without the unnecessary bulk. ASRock has managed to pack high-end components into a compact chassis, making powerful computing accessible to anyone who values both efficiency and form factor.

Beyond the immediate performance, the system is built with future-proofing in mind. Flexibility is key, and the NUC BOX-358H delivers on this promise through modern connectivity and internal architecture.

Adding further versatility, the system is equipped with dual 2.5 GbE network ports, providing the connectivity needed for a smooth, high-speed digital workflow.
