You've got the drive and the optical unit sitting on your bench, but no clean way to mount them in the ST45 V3. This cage kit slots straight into the chassis and holds one 3.5-inch HDD alongside an ODD without dremel work or improvised brackets. It's a genuine Lenovo ISG part, so the fit is exact. No guessing which screws go where. Drop it in, seat the drives, done
