Following their Business-Grade Cyber X1, all MeLE's fanless mini PCs, including the PCG02, PCG02 Pro, and the Quieter 4C, now come with a Business-Grade sticker. While the new Cyber X1 includes a physical SO-DIMM RAM slot, these three models lack visible hardware changes. However, internal components, such as capacitors or the power supply, may have been upgraded to support the advertised 24/7 operation.
