Mislabeled 2U 12 Bay Server Chassis

I can’t find any model numbers but it’s mislabeled

the chassis in the pictures is a custom version of AIC RSC-2EH

AIC build quality is similar to Chenbro, better than Norco.

I know this an old thread so I apologize. I just ordered one of these cases. From the looks of the doc, the case seams to have the 1x12 sas with 4 8088 28-phy expander. Would this work as a regular expander needing a single 8088 to sas controller or does it operate as simply built in breakouts? Each 8088 would run 4 drives?
