The Lenovo 4M17A12096 is a drive bay conversion kit for the ThinkSystem ST50 tower server, adapting the chassis's 5.25-inch optical bay to accept a 3.5-inch hard disk drive alongside a slim optical disk drive. If you are expanding storage in an ST50 without sacrificing ODD access — for recovery media, OS installation, or backup — this kit is the factory-matched solution. Without it, the 5.25-inch bay simply cannot seat a 3.5-inch drive in a mechanically sound or thermally proper configuration. The 4M17A12096 eliminates the need for generic adapter workarounds that can interfere with airflow or vibration dampening in a server-class enclosure.
Designed specifically for the Lenovo ThinkSystem ST50 tower server. This kit is not a universal adapter — it is engineered to the ST50's internal bay geometry, mounting points, and cable routing. Do not attempt to use it in other Lenovo tower or rack server families (SR/ST150/ST250/ST550 series) without verifying Lenovo's compatibility matrix, as bay dimensions and sled mechanisms differ across generations. Confirm your ST50 chassis revision before ordering if you are working with mixed-vintage units in a server infrastructure deployment.
The kit weighs 1.40 lb and its external dimensions are 10.50 × 9.00 × 5.00 inches, consistent with a full 5.25-inch bay adapter assembly. Plan for standard tower server access — side panel removal and bay release. No specialized tooling is documented in the available evidence beyond what standard ST50 service procedures require. Consult the ST50 Hardware Maintenance Manual for torque specs on drive sled fasteners before finalizing installation in a production environment.
