extending to another case

[Jackal24]

I currently have a 12 Bay hotswap case (rosewill). I am thinking of adding another one of the same, or possibly a Norco. What do I need to run the drives in the second case (SATA drives)? I know I will need another controller card, but what cables do I run to the new case from the old one? If I use another rosewill case, the drives have individual SATA connectors so I will probably need breakout cables, but I'm assuming I don't need to run 12 SATA cables from one case to the other.

Only if you use an expander, that would also allow you to use cables longer than 1 meter, something like this:

What are the different cards I see there (3 in total)?

The bottom one is an SFF-8088 to 8087 adapter like this:

Then larger middle one is the  SAS expander, the top one is optional, it's just to power on the second power supply, you can e.g. use a paper click and power it on using the button on the back of the PSU.
