Especially the base model of the 24-inch iMac is a bit stingy with ports: Apple only provides two USB-C ports. If you need more ports after a while – including USB-A, which will probably never die out – you either need a hub underneath the iMac or you simply attach one to the back.
This is what Belkin thought of the 6-in-1 multiport hub. All ports are located on the right side, just like on old iMacs (like the drive and SD card slot back then). Thus, you have two USB-A and one USB-C port as well as a (micro)-SD card. On the inside of the hub, there is also a practical Ethernet port, which the smallest iMac does not have.
Those who missed the opportunity to buy the four-port version of the iMac can now make up for the strategic mistake for about 60 Dollars. Whether the hub is visually a feast for the eyes remains to be seen. We leave that to the eye of the beholder.
