Simple mount for a third SSD for Antec P101 Silent. It uses two mount location that were (probably) intended for a HUB of some sort.

It needs two short ish mount screws to the mainboard tray. The screws must be short as you could shor the mainboard itself. My suggestion is to mount the SSD tray first and then check if everything is in place.

Before mounting the other SSDs and cable manage you should mount the SSD in the holder too. It is not the easiest design to manage if you swap the drives frequently.

A flexible scredriver extension might be helpful if you case is already in production.
