ZOTAC ZBOX CI345 N150 Fanless Barebone Mini PC - Intel Celeron N5100, 2x GbE, HDMI/DP/VGA, Wi-Fi 5, No RAM/Storage

Silence meets versatility in the ZOTAC ZBOX CI345 N150, a fanless barebone mini PC engineered for 24/7 operation in noise-sensitive environments. Unlike typical compact desktops that rely on active cooling, this system dissipates heat passively, eliminating dust buildup and moving parts for enhanced reliability. Powered by an Intel Celeron N5100 quad-core processor, it delivers responsive performance for digital signage, thin client computing, and light office workloads. Dual Gigabit Ethernet ports and triple display outputs make it a flexible hub for multi-monitor productivity or network appliance deployments.
