philpem, Finished off the microscope software this morning, so it's onto the next project - the new network router. My old 1U MiniITX is showing its age in several ways, and this is the upgrade. A HP T730 thin client with an Intel 4-port network card. Quad core AMD RX-427BB.
No SSD installed on arrival, so I picked up an open-box WD Green 240GB. Massive overkill for OPNsense, but it was cheap.
