GoKawiil's interpretation of the reporting above, not reported fact.
The NucBox G9 has become popular as a compact OpenWrt router, but its onboard eMMC storage and limited native networking raise reliability concerns for users relying on it as critical infrastructure. Because the G9 is now discontinued and hard to source, this DIY expansion offers existing owners a way to extend the device's usefulness rather than hunting for an increasingly expensive replacement.
- The mod adds four Intel I226-V 2.5GbE NICs to the NucBox G9 using a custom 3D-printed part.
- Files for the print are shared publicly so other owners can replicate the upgrade.
- The project stems from concerns about eMMC reliability and the G9 being discontinued amid rising mini PC prices.
