This 3.5" faceplate insert is designed to fit into an empty drive bay. It is dimensionally similar to a standard 3.5" floppy drive in terms of height, width, and hole spacing.

It presents an attractive smooth front facia to fill an empty drive bay.  No need to find the exact snap in front insert for your case.

This version is designed to accept M3 brass heat set anchor inserts to secure it to the slotted drive bay chassis.

This design solves the age old issue finding a proper fitting face plate for a vintage computer case.
