Fanless Zbox Mini PCs Bring Intel Wildcat Lake
Three barebone nano systems use Intel's new low-power chips in passively cooled cases, with pricing and shipping dates still unannounced.
Updated on Nov. 2, 2026 in Computers
Zotac has unveiled three fanless Zbox C-series nano mini PCs built on Intel Wildcat Lake processors: the CI431, CI451 and CI471 nano, using the Intel Core 3 304, Core 5 320 and Core 7 350 respectively. The systems are listed as barebone units, so buyers must supply their own memory and storage. The CI471 nano was first spotted at Computex 2026 in June without a full specification sheet; the products are announced, not yet shown in shipping reviews.
Why it matters
The launch extends Intel's Wildcat Lake platform into compact, passively cooled desktops, a segment where thermal limits and small chassis size constrain performance. It signals that Intel's newer low-power processor line is moving from reference designs into third-party small-form-factor systems.
The manufacturer lists a 204 × 129 × 68 mm passively cooled chassis of about 1.79 litres, one DDR5 SO-DIMM slot up to 64 GB, one PCIe 4.0 x4 M.2 2280 slot, two Thunderbolt 4 ports and a 2.5 Gbps wired port. No benchmark results or power figures were provided.
The players
Zotac
Zotac is a graphics-card and compact-PC maker whose Zbox line focuses on small-form-factor desktops built on Intel and Nvidia platforms.
Intel
Intel is the largest x86 processor maker, and its Wildcat Lake chips are the low-power processors inside the new Zbox systems.
The details
The three models share a fanless chassis, so heat must leave through the case rather than through fans, which limits sustained clock speeds under heavy load. Each unit takes one DDR5 memory module and one M.2 storage drive, and the systems ship without either, so the buyer chooses the final configuration. Connectivity includes Wi-Fi 7 with Bluetooth 5.4 and a mix of Thunderbolt 4, USB 3.2 Gen 2 and USB 2.0 ports.
Timeline
June 2026: the CI471 nano first appeared at Computex 2026 without a full specification sheet.
November 2, 2026: Zotac announced the three Zbox C-series models.
The Tech Race
Zotac's fanless Zbox systems place Intel's Wildcat Lake chips against the compact desktop market, where rival chip families compete on performance per watt. The CI360 nano, with dual M.2 slots and dual Ethernet, shows the same platform being packaged for different buyers.
Buyers who want a silent, compact desktop can plan on purchasing the barebone units and adding their own DDR5 memory and M.2 storage. Pricing and shipping dates were not disclosed, so timing for purchase is unconfirmed.
The takeaway
Compact fanless PCs remain limited by sustained-load thermals, so the first independent thermal and benchmark tests of the CI471 nano will show how much performance the Core 7 350 keeps without a fan. Watch for pricing and availability announcements from Zotac for the three models.
