What owners say
Two Japanese writers had the NucBox 5 with the Celeron N5105 in 2022 — one reviewed it with a teardown, the other bought it on sale and used it for months — and the version sold now may differ: their units had a Wi-Fi 6 card, while the current listing says Wi-Fi 5. The 8 GB of memory is soldered and ran single-channel, which the owner found the main limitation for a main PC. The fan runs at one constant speed from idle to full load, 37 dB against 35 with the PC off: very quiet by the reviewer's reckoning, a constant whoosh to the owner. It draws 6.3 W at idle and under 20 W at peak, with the processor touching 94 °C while the case stays around 35 °C. The power adapter has a USB-C plug but puts out a fixed 12 V, which breaks the USB standard, and both writers warn it could damage another device plugged into it. The microSD reader is slow, around 20 MB/s. The M.2 2242 slot appears wired for NVMe as well as SATA, untested. The reviewed unit shipped with Windows 11 Home. For blogging, office apps and browsing the owner found it fine; its weak points were expansion, with two HDMI and three USB-A ports, and fan noise.
- For whom
- Light office work and browsing at the lowest price.
- Not for
- A main PC for anything beyond light work. Never charge another device from its power adapter.
