Compatibility & preservation notes
HP-specific board/PSU, tool-less retention and cooling; PCIe cards depend on CPU/riser/slot/PSU combination. Not an ATX donor case without modification.
Heavy chassis: safe lift; retain airflow baffle, fan modules, PCIe hardware and drive cables. Follow HP service procedures around PSU and boards.
- Record the complete model/SKU, serial/date label, board and bay/backplane identifiers, accessories and manual revision before disassembly.
- For servers/workstations, match the exact riser, backplane/controller, drive carrier, PSU and rail kit; a matching 2U/4U height alone does not ensure compatibility.
- Keep original brackets, fasteners, trays, feet and front-panel parts labeled with the chassis. Do not force components into modified or incomplete specimens.
