Checked on 2026-10-29 against 2 sources: verified. Beetstech lists PPNs 820-2993-A and 820-3017-A for its Mid 2011 Mac mini logic board (compatible: Macmini5,1 MC815LL/A 2.3 GHz i5, Macmini5,2 MC816LL/A 2.5 GHz i5 and BTO 2.7 GHz i7, Macmini5,3 Server MC936LL/A) and gives PPN 820-2993-A on its 2.7 GHz i7 (661-6376) board; an eBay listing ties 820-2993-A to the 2.3 GHz Core i5 board. Apple's spec page: 2.3 GHz has Intel HD 3000, 2.5 GHz has Radeon HD 6630M; no source maps PPN to graphics configuration. Consistency review: identifier separator changed from 'Macmini5,1; Macmini5,2' to 'Macmini5,1 / Macmini5,2' to match the other multi-identifier rows. Revision A is a placeholder until Studio records the real revisions.
