Zotac quietly makes its new fanless Wildcat Lake mini PCs official

Zotac has shown off three new Zbox C-series nano mini PCs powered by Intel’s Wildcat Lake processors. They feature completely passive cooling, plenty of connectivity options, and support for up to 64 GB of DDR5 memory.

The lineup comprises the Zbox CI431 nano, CI451 nano, and CI471 nano. These are powered by the Intel Core 3 304, Core 5 320, and Core 7 350, respectively. The CI471 nano was first spotted at Computex 2026 back in June, although Zotac had not provided a complete specification sheet at the time. The newly surfaced product listings confirm its processor configuration alongside two additional Wildcat Lake-powered models.

All three mini PCs share a passively cooled chassis measuring 204 × 129 × 68 mm, with a volume of approximately 1.79 litres. Despite their compact dimensions, Zotac has managed to accommodate a single DDR5-6400/5600 SO-DIMM slot supporting up to 64 GB of RAM. Storage is handled by one M.2 2280 PCIe 4.0 x4 slot.

Connectivity includes two Thunderbolt 4 ports, two USB 3.2 Gen 2 Type-A ports, and three USB 2.0 ports. Display outputs include HDMI 2.0b, DisplayPort 2.0, and DisplayPort over Thunderbolt 4, allowing users to connect up to three 4K monitors at 60 Hz. Wireless connectivity is handled by Intel’s Wi-Fi 7 module alongside Bluetooth 5.4, while a 2.5 Gbps port provides wired networking.

Compared to the previously covered Zbox CI360 nano, the new models offer more powerful processors and upgraded connectivity. However, the CI360’s dual M.2 slots and dual Ethernet ports have been replaced by a single storage slot and one Ethernet connection. The Wildcat Lake models are also noticeably larger than the 0.9-litre CI360.

Zotac lists all three machines as barebone systems, meaning buyers will need to supply their own memory and storage. Pricing and regional availability have yet to be announced.
