5.25" to 3.5" bay adapter

The ICY DOCK MB343SPO converts a single 5.25 inch external bay into space for one 3.5 inch SATA drive and one 9.5 mm ultra-slim optical drive. A screw-less Smart-Tip locking mechanism secures the 3.5 inch device while a guiding system eases insertion. Snap-off dust covers keep both openings clean when not in use. A 6-pin Slimline to 15-pin SATA power cable is included.

For builders adding legacy storage

This bracket suits system integrators or enthusiasts who still use 3.5 inch hard drives or slim optical drives in modern chassis with a free 5.25 inch bay. It is not for builders who only have 3.5 inch internal bays available or who need to install 2.5 inch drives without a separate adapter. It also cannot serve cases that lack a 5.25 inch half-height opening.

Single 5.25" bay conversion

The decisive specification is the one-to-two device fit: exactly one 3.5 inch SATA drive and one 9.5 mm ultra-slim ODD share a single 5.25 inch half-height bay. If the build requires two 3.5 inch drives or a full-height optical drive, this bracket will not accommodate them.

  • Snap-off front panel dust covers protect both the 3.5" and optical bays

Questions about this item

Will this bracket fit into a standard 5.25" external drive bay in my case?

Yes, the MB343SPO is designed for any standard 5.25" half-height external bay measuring 148.80 x 145.80 x 41.30 mm.

How does the Smart-Tip locking mechanism work for screw-less 3.5" drive installation?

Slide the 3.5" drive into the tray until the Smart-Tip tabs click into the drive's side mounting holes, securing it without screws.

Do the snap-off front panel dust covers need periodic cleaning or replacement?

The dust covers are fixed plastic parts; simply wipe them with a dry cloth if dust accumulates — no replacement is required.
