This is a 3d printed case for housing a Greaseweazle 4.1 board and a 3.5" floppy drive and two 5.25" floppy drives. The reason for having two 5.25" drives is to house a 360k drive and a 1.2mb drive. It comes with a floppy cable and 21 screws and does not include a Greaseweazle board or any floppy drives or a power supply. You could use this https://www..com/itm/326421321797 power supply and it will probably work if you're only using the drives to read/write image files but I would recommend a PSU with at least 4 to 5 amps at 12v and 2 amps at 5v if you're going to use the drives for random access using all 3 at once. You may have to hack together a 12v psu and a 5v psu and combine them into an external power brick and patch together a power cable with 3 molex connectors. Alternatively, this can house a full height 5.25" drive, but specify you want this for that purpose because the mounting holes are different.
