On the current version, there is a screw that is already available on the 2nd M2 slot of the MSI Z590 motherboard. For the SATA disks, they are mounted on the right side of the PC and there are 2 brackets available and there is a pack of screws that come with the PC as an accessory.

According to our product experts, there is room in the case for another 2.5" SSD, as well as room on the motherboard for another M.2. The cables are not included, however, and will have to be purchased separately, as will the screws.
