You have 1 to 1, 2 to 3, 3 to 4 and 4 to 5. Mix and match to fill all 5 bays with best density of 3.5 inch bays.  Here is one example and I am sure you can find many. https://www.newegg.com/p/pl?d=hot+swap+bay&N=100007599%20600551589&name=SSD+%2F+HDD+Accessories&Order=4 I have three cages, two istar and 1 icy doc. My icy dock lost one bay. The others are holding a bit better. So, YMMV. However, expect them to have noisy fans. You may want to change to quieter/reliable ones. Regards Ramesh
