I needed some way of fixing 2 2.5"drives inside the case of my Fujitsu Futro S930.

This thing can hold 2 drives, the bottom one with two screws, the upper one upside down with three screws.

The holder has small Ts on the bottom to slide into the metal bracket which is next to the motherboard and normally holds things like a PoE module, a speaker or a smartcard reader. It's fixed to the bracket by one screw.

When assembling you have to this in a particular order:

1. First remove the metal bracket from the case.
2. Slide in the holder and put in the one screw to fix it to the bracket.
3. Insert the lower drive and put in the two screws from underneath (then you'll see why it's only two screws holding it)
4. Insert the upper drive and fix it.
5. Mount the bracket with the drives in the holder back into the case.

Steps 4 and 5 are interchangable, there should be enough space to hold the drive and screw it to the holder.

Since I don't have a PoE module at hand I can't say for certain if it still fits with the drives plugged in, but what I know for sure is that there is enough clearance to the top to still insert a PCIE card with a low profile (things like a graphics card won't fit, but a USB or NIC should be fine)

During it's several iterations I found out that the small T sliders are quite fragile, so moving the entire model up by 2mm from the build plate helped with them not snapping of, since there are supports underneath them which you need anyways.

Also worth noting is that I've only tested the holder with SSDs which are quite light. Even though HDDs should fit fine (even the tall ones) I'm not sure how the posts holding the upper drive will hold up with the mass.
