I got 4 x CBL-SAST-024 since connections are going to the SATA ports in the motherboard. I just ordered also 1 x CBL-0157L for SGPIO.I personally took off the cover/fan to plug everything in, it was a pain in the ass to get SAS cables in there.
I just used a SAS 8643 to 4 SATA/SAS break out cable with no side band:
You could easily do the same with a 8087 connector.
