Used Dell mini PCs
Dell's OptiPlex line of business desktops launched in 1993 and ran for more than three decades, built for corporate, government, healthcare and education buyers. Its Micro models, such as the OptiPlex 3060, 5060 and 7060 Micro, are 1-liter PCs that turn up widely on the used market. On January 6, 2025, Dell announced it was consolidating its PC brands and folding OptiPlex into the new Dell Pro line, so recent business micro desktops carry Dell Pro names instead. Within one generation, the 3000, 5000 and 7000 Micro models are different machines, so check each one's spec sheet for memory, storage and networking.
