I have purchased for and/or recommend several of these units for clients. Some are being used as desktop PCs for office applications. Others I've configured for network file sharing or backup servers for small offices having 3-6 workstations using Ubuntu Linux. Several were re-painted with flat black spray paint, but they were still in acceptable enough condition to be placed on a desk as a monitor stand. In the case of using them as file servers I did change out the original M.2 drives for a popular brand with high ratings, installing two of them as a redundant RAID mirror.
