Enclosure specifications
| Exact model / generation | Apple Macintosh IIcx (Model M5650, 1989); original compact six-slot system, not Macintosh II/IIx/IIci. |
|---|---|
| External dimensions | About 14.4 × 10.9 × 6.0 in (W × D × H) for the system unit, reported; measure feet, case handle/cover and rear clearance on the actual specimen. |
| Form factor / board layout | Compact horizontal desktop with a proprietary internal logic-board/NuBus cage arrangement; separate monitor, Apple-specific case and fan/airflow path. |
| Proprietary power supply | Internal proprietary Apple IIcx power supply, fan and harness; not an ATX replacement. Correct output connectors and airflow are model-specific. |
| External bays / ports | No standard external drive bays. Rear slot openings and I/O ports do not constitute drive bays. |
| Internal bays / mounts | One 3.5-inch floppy mechanism and internal hard-drive carrier position in typical builds; carrier and installed drive options vary by configuration. |
| Service / compatibility | Use Macintosh IIcx Service Source and Apple hardware reference. Keep supply/fan, logic board, internal cabling and shields matched; service CRT only if a separate display is disconnected and handled properly. |
| Revision identification | Identify Model M5650 and logic-board revision. Do not assume Macintosh II/IIx PSU, case or drive carrier interchangeability merely because NuBus cards share a standard. |
