Affiliate disclosure. Mini-PC Index intends to earn commission from links to vendors. No affiliate programme is configured yet, so every outbound link on this page is a plain, untagged vendor link and earns nothing. When that changes, commissions will never affect which machines are listed, what the data says, or how the table ranks.
