You're running the ST50 and you've hit the drive limit. That second cage isn't a luxury — it's how you stop juggling external storage while your workloads grow. This kit drops into the ThinkSystem ST50 V2 or V3 chassis and gives you a second row of 3.5" HDD bays. No third-party adapter, no 'will it fit' gamble. It's the Lenovo part, made for that slot. Pull the existing cage, seat this one, drop in your drives. Sorted
