The Dell OptiPlex 3000 Micro fits both M.2 2230 and 2280 drives

The Dell OptiPlex 3000 Micro accepts both M.2 2230 and 2280 form factors in its NVMe slot — handy if you’ve got a smaller drive lying around. It also squeezes in a 2.5-inch SATA bay for a second drive. Dell doesn’t expose additional SATA ports externally, so the bay is your only SATA option.
