Cirrus7 Incus B860 fanless mini PC ships with Intel Core Ultra 200S, Linux options

Cirrus7 has released the Incus B860, a fanless mini PC built on the ASRock DeskMini B860 platform that accommodates Intel's Core Ultra 200S desktop processors with up to 24 cores. The system uses a passive aluminum heatsink enclosure with copper cores, available in three height variants offering increasing thermal capacity for different workload profiles. Memory support reaches 64GB of dual-channel DDR5-5600 via two SO-DIMM slots, while storage options include two M.2 NVMe slots (PCIe 5.0 x4 and PCIe 4.0 x4) plus two additional 2.5-inch SATA bays.

The Incus B860 offers substantial I/O connectivity including Thunderbolt 4/USB4 at 40Gb/s, 2.5 Gigabit Ethernet, HDMI 2.1, multiple DisplayPort 1.4 outputs, and USB-C 3.2 at 20Gb/s. Wireless options include Intel Wi-Fi 6 with Bluetooth 5.2. Critically for FOSSWire readers, Cirrus7 offers Ubuntu and Linux Mint as factory operating system choices alongside Windows 11 or bare metal delivery, with the company explicitly targeting Linux users in its configuration options.

Hardware architecture and Linux compatibility

• Processor platform: Supports Intel Core Ultra 200S series with hybrid P-core/E-core architecture, ranging from 10-core Ultra 5 225T to 24-core Ultra 9 285T, all with 35W base TDP (T-suffix) and integrated Intel Graphics.
• Memory subsystem: Two SO-DIMM slots supporting dual-channel DDR5-5600 or DDR5-4800, with maximum capacity of 64GB; this is standard notebook-style memory in a desktop processor context.
• Storage expansion: Two M.2 NVMe slots with PCIe 5.0 x4 and PCIe 4.0 x4 interfaces respectively, plus two 2.5-inch SATA SSD positions, allowing four total storage devices with passive cooling for the NVMe drives.
• Thermal design: Three enclosure heights (124mm, 148mm, 172mm) share a 202 x 179mm footprint, with larger variants providing additional aluminum fin surface area and copper core mass for sustained workloads.
• Linux support status: Ubuntu and Linux Mint are offered as preinstalled operating systems, indicating Cirrus7 has validated these distributions on the Intel B860 platform with Core Ultra 200S graphics and I/O.

Why it matters

Fanless x86 systems with modern hybrid-core processors remain relatively uncommon, and the Incus B860 fills a niche for Linux users needing silent operation in studio, medical, or industrial environments where dust and noise are concerns. The explicit Ubuntu and Linux Mint factory options, rather than aftermarket installation, signal vendor commitment to Linux compatibility on Intel's newer desktop platforms and reduce validation burden for deployment. However, prospective buyers should note that Intel Core Ultra 200S graphics and power management on Linux are still maturing compared to the extensive support for 12th-14th Gen Core processors.
