Memory-heavy stress exposed a cooling limit
Jeff Geerling reported overheating and inconsistent results in a 7-Zip benchmark on his review unit. Repasting did not fully resolve his concern; removing the cover and adding airflow let him complete consistent comparisons. His later benchmark results use that modified cooling setup.

24/7 qualification Manufacturer-qualified for 24/7 use
MSI says the Cubi NUC AI+ 2MG family is qualified for 24/7 operation and cites more than 246,000 hours of mean time between failures. This is a manufacturer reliability claim, not an independent long-term failure-rate measurement.

MSI -
Repairability tradeoff SSD serviceable; RAM fixed
The SSD and wireless module are serviceable, but the processor-package memory is permanently fixed. A memory failure therefore requires motherboard-level service rather than a DIMM replacement.
