This case has three external 5 ¼” bays, one external 3 ½” bay, six internal 3 ½” bays and one internal 2.5” bay. Only the first 5 ¼” and the first internal 3 ½” bays use a screwless mechanism, so you need to use screws to install drives on the other bays. At least Element T comes with thumbscrews, so no tool is needed to install the drives (it comes with both thin and thick thumbscrews, so you can use thumbscrews on 5 ¼” and 3 ½” drives).

The 2.5” bay may not be noticed by most users. It is simply a bunch of four holes located on the bottom of the case. Even though it is located below the hard disk drive bays, you can install a hard disk drive or an SSD there and have a hard drive installed on the bottom bay at the same time without any problem.
