Barebone mini PC ASRock NUC-Box-155H — compact barebone system (model NUC-Box-155H)

The ASRock NUC-Box-155H is a compact barebone mini PC kit designed for assembling a small desktop system. Supplied as a chassis with integrated mainboard, it requires the user to install a compatible CPU, memory modules, storage drives and an operating system. The design focuses on a reduced footprint and flexible internal layout to support typical home, office and commercial deployments where space and configurability matter.

Advantages

This barebone approach lets users tailor system performance and capacity by selecting the CPU, RAM and storage appropriate to their needs. The integrated mainboard and compact chassis simplify installation and cable management while retaining options for upgrades. The low-profile form factor and efficient internal layout make it suitable for tight workspaces and installations behind displays or under desks.

Suitable for

• Home desktop systems with customizable performance
• Office workstations for productivity and light multitasking
• Digital signage and kiosks where a small footprint is required
• IT environments that need compact, upgradable endpoints

Key specifications

• Form factor: compact mini PC barebone with integrated mainboard and chassis
• CPU: user-supplied compatible processor required
• Memory: user-installed DIMM modules (capacity and speed depend on chosen modules)
• Storage: user-installed drive bays/slots for SSD/HDD (supports appropriate 2.5" or M.2 depending on board)
• Expansion and I/O: multiple external ports and internal connectors on the integrated mainboard for peripherals and upgrades
• Power: external or internal power solution provided depending on configuration; requires compatible power adapter or PSU
• Use case suitability: designed for home, office and commercial compact installations

How to use

Install a compatible CPU into the onboard socket following the processor maker's instructions and apply thermal solution as required. Insert memory modules into the available DIMM slots and install storage devices into the indicated bays or M.2 slots. Connect necessary external peripherals, attach the appropriate power supply, and complete BIOS/UEFI setup. After hardware installation, install the desired operating system and drivers to enable full functionality.

Recommendations

Choose a processor and memory configuration that match intended tasks: low-power CPUs and modest RAM for light office use, or higher-performance CPUs and greater memory for multitasking and heavier workloads. Use an SSD for the system drive to improve responsiveness in compact systems. Ensure adequate cooling clearance around the chassis and keep BIOS/firmware up to date for compatibility and stability.
