Data cables for HL 15

I’m getting ready to pull the trigger on an HL 15. My plan is to purchase the Chassis, Backplane, and PSU. I currently have a Truenas server with an AsrockRack X570d4u that I plan on just moving over there and taking the 3 SSDs and dropping them in, plus more. My question is what data cables should I pick out? I watched Level1s video and I think I may need an HBA card. curious if anyone has a similar build or some knowledge as my knowledge about SAS Sata etc… isn’t the best

Yes, you do need an HBA to control all those drives, I would post in their forums.
