Hi, I'm using a Lenovo ThinkCentre M920s SFF as a small homelab server and I'm trying to find a clean way to mount a fourth 2.5" SATA SSD/HDD in the optical drive area. The other drive positions are already occupied: 2x 2.5" drives mounted in the 3.5" drive cage 1x 2.5" drive in the original Lenovo 2.5" caddy That leaves the optical drive area as the only realistic place for the fourth SATA drive. I already tried a standard slim optical-drive-to-2.5" caddy, but it doesn't fit properly in the M920s. The rear of the caddy hits the fan directly behind the optical drive bay. Also, since the front panel of my M920s has no opening for the optical drive, the caddy can't slide forward far enough to latch into place. There is enough space for a single 2.5" drive itself, so ideally I'm looking for a much shorter and simpler 3D-printed bracket/cage that only holds the drive and uses the existing space or mounting points. Has anyone already designed something similar for the M920s or another ThinkCentre with the same chassis? I'm mainly looking for an existing STL/CAD file or another clean mounting solution. I can provide detailed photos and measurements of the available space and mounting points if needed. Thanks!   submitted by   /u/leymic10   to   r/3DPPC [link]   [comments]
