Other configurations in the MIC-300 series
Same chassis, same mounting — they differ in screen size and CPU. If the model above isn’t quite right, switching to one of these is usually enough.
Equivalent products from other series
Different series — some even a different brand — but the same machine type with closely matching key specs. We cross-check compatibility against the manufacturer’s documentation before quoting.
