✎
If you are installing a drive in the bottom 5.25" drive bay, remove the
metal shield that covers the bay by pressing inward on the silver tab
on the left side of the chassis then pulling the shield out from the front
of the chassis.
✎
There are a total of eight extra guide/retainer screws on the front of
the chassis behind the bezel. Four have 6-32 standard threads and four
have M3 metric threads. Standard screws are used for hard drives and
have a silver finish. Metric screws are used for all other drives and
have a black finish. Be sure to install the appropriate guide screws
into the drive.
