Compact barebone with Core Ultra 7 155H

The ASRock Industrial NUCS BOX-155H is a slim fanned barebone mini PC built around the Intel Core Ultra 7 155H processor with six performance and eight efficient cores. It arrives without memory or storage so integrators can configure the system for specific workloads.

Suits builders adding their own DDR5 and SSDs

This unit fits teams that want to choose SO-DIMM capacity up to 96 GB across two 262-pin slots and select M.2 drives for the two Key M slots. Buyers needing a complete out-of-the-box system with pre-installed RAM or a 2.5-inch drive bay should look at a different form factor.

Two M.2 Key M slots with PCIe Gen4

The platform provides one 2242/2280 slot at PCIe Gen4 x4 and a second 2242 slot at PCIe Gen4 x1. This layout decides whether the storage plan fits, because no other internal drive interfaces are present.
