Dell is a good, quality machine in the 3020 micro realm, especially if you want to build a NAS server using an external HDD box such as Mediaplex's PROBOX. In this configuration, I have 6 NAS servers in front of me. I use UBUNTU 22.04.4 with a software RAID-1 configuration. The 3020 mini(s) I bought were clean, with one sent with a power supply that was too weak for the computer.
