GMKtec Mini PC NucBox G5 - Compact 4K Mini PC Computers

In this review of the GMKtec Mini PC NucBox G5 we look at who will benefit most from this tiny desktop and why its combination of the Intel 12th Gen N97 and compact design stands out. The bottom line: this is a well-rounded, ultra compact mini computer for home, office, or light workstation use where quiet operation, efficient power draw and dual 4K output matter most. The N97 CPU and upgraded Intel UHD GPU deliver noticeably better performance than earlier N-series chips, while the small pocket-sized chassis makes it easy to tuck behind a monitor or carry between rooms.

Key Features

• Processor: The Intel Alder Lake N97 (4C/4T, up to 3.6GHz) gives a clear performance uplift over older N-series chips for everyday multitasking and media playback.
• Graphics and display: Dual HDMI outputs support 4K UHD at 60Hz so users can run two high-resolution monitors for productivity or media without stuttering.
• Memory and storage: 12GB LPDDR5 RAM with a 256GB M.2 SSD provides snappy boot times and responsive app loading for typical office and home workloads.
• Connectivity: Multiple ports including 3x USB 3.2, Gigabit RJ45, micro SD and Type-C power make it simple to connect peripherals, wired networks and external storage.
• Size and cooling: One of the smallest mini PCs available with a quiet cooling fan that remains minimal under light to moderate load, ideal for noise-sensitive environments.
• Power features: BIOS options such as Auto Power On and Wake on LAN allow basic headless or always-on uses in a home server or office kiosk role.

Who It's For

The NucBox G5 suits users who need a discreet, low-power desktop for general office work, web browsing, media streaming and light productivity across two displays. It is a good fit for students, remote workers and small business deployments where space is limited and quiet operation is prized.

It is less suitable for heavy gaming, 3D rendering or high-end content creation because the integrated GPU and 4C/4T configuration target efficiency and everyday responsiveness rather than sustained high-end workstation throughput. Buyers seeking a larger SSD or upgradable RAM should also consider machines with modular slots.

Pros & Cons

Pros

• Compact footprint with notably quiet cooling for concentration-friendly operation.
• Improved CPU and GPU performance from the Intel N97 for faster responsive multitasking than previous N-series models.
• Dual HDMI 4K@60Hz outputs and Gigabit Ethernet enable productive multi-monitor setups and reliable wired networking.
• Ample I/O including multiple USB 3.2 ports and micro SD for easy peripheral connections.

Cons

• On-board 12GB RAM is fixed, limiting future memory upgrades compared with some modular mini PCs.
• Storage is a single 256GB M.2 which may require expansion for heavier media libraries or large project files.

Our Verdict

The GMKtec NucBox G5 is a compact, quiet and efficient mini PC that delivers tangible improvements in daily performance thanks to the Intel N97 and a boosted iGPU. It is excellent value for anyone needing dual 4K displays, low noise and solid connectivity in a tiny package, though users who require expandable RAM or larger internal storage should plan to add external drives or choose a different chassis.

Frequently Asked Questions

Can this run two 4K monitors?
Yes. The NucBox G5 has dual HDMI ports that support 4K UHD at 60Hz for dual-display setups.

Is the fan loud under load?
Customers report the fan is mostly inaudible at light load and remains fairly quiet even under heavier use.

Can I upgrade RAM or SSD?
The RAM is on board at 12GB so it is not user-upgradeable; the M.2 SSD can be replaced if you need more storage.
