Compact barebone for Intel Core Ultra Series 2

The ASRock Deskmini B860W is a 1.92L barebone that accepts Intel Core Ultra Series 2 processors in the LGA1851 socket up to 65W. It ships without memory or storage, giving builders a clean slate for a small-form-factor desktop. Integrated Intel Graphics drive up to four displays through HDMI 2.1, two DisplayPort outputs and Thunderbolt 4. A Wi-Fi 6 module is included in the M.2 2230 slot.

Suited for multi-display offices and edge AI

This platform fits smart offices, digital signage, edge AI gateways and hybrid workspaces that need quad video output and 2.5Gbps LAN in a minimal footprint. It is not for buyers who want discrete graphics performance, more than two SO-DIMM slots, or a chassis that accepts full-size expansion cards. The 65W CPU ceiling also rules out high-wattage workstation processors.

Straightforward assembly with laptop-style parts

Installation uses standard SO-DIMM modules and M.2 2280 SSDs secured by screws; the CPU cooler mounts with the supplied bracket. The tight interior makes cable routing the main challenge — SATA cables for 2.5-inch drives must be folded carefully. Builders should verify DDR5 SO-DIMM or CSODIMM compatibility before purchase, as the board does not support older memory types.

Questions about this item

What DDR5 SO-DIMM modules and maximum capacity do I need to install for this DeskMini B860W to work?

You must supply two DDR5 SO-DIMM modules, up to 128 GB total, running at 5600 MHz or CSODIMM at 6400 MHz with overclocking up to 7200 MHz.

Can I keep my existing SATA 6.0 Gb/s drives and Wi-Fi 6 module when building this barebone?

Yes, the board provides two SATA 6.0 Gb/s ports and an M.2 2230 slot that accepts a Wi-Fi 6 and Intel CNVi module.

How do I confirm the quad video outputs and Thunderbolt 4 port are active after assembly?

Connect displays to the HDMI 2.1 and two DisplayPort connectors, plus a Thunderbolt 4 device; all four should signal simultaneously if the installed Core Ultra processor supports them.
