Internal Drive Bays

Internal Drive Bays

These bays are entirely within the case and are not accessible from the outside. If a device does not require any access from the outside it is preferable to use an internal bay, and save the case's external bays for drives that need them. In practical terms, this means that internal drive bays are usually used for hard disk drives, which do not require any access by the user.

and one internal drive bay (on the bottom.) On a system like this, to
use two hard drives one would normally mount the second one into
an external drive bay and simply leave the cover for that bay in place.

You can of course mount a hard drive into an external drive bay. So in some ways, an internal drive bay is really an "internal only" bay. Some cases in fact do not have any internal drive bays; hard drives are mounted into external drive bays and solid faceplates left to hide the drive from the outside.
