This case has four external 5 ¼” bays and seven internal 3 ½” bays for hard disk drives. Even though we can see holes on the middle of the 5 ¼” bays for installing screwless retention mechanisms, this case doesn’t come with them. On the other hand, this case comes with several thumbscrews for fastening 5 ¼” devices, so you don’t need to use any tool to install them.

As for the 3 ½” bays, two of them are located between the 5 ¼” cage and the main hard disk drive cage and they don’t use any kind of screwless retention mechanism. However, only one of these bays can be used (the bottom one), because the front panel connectors make it impossible to use the top bay.
The five 3 ½” bays present on the main hard disk drive cage use a screwless mechanism based on rulers that need to be installed on the sides of each drive.
