Differential SCSI vs. SE ?

Is the HSZ40C in a StorageWorks brick, or is it built into a tower? The
reason I'm asking is because my HSZ20 is a tower (with dual power
supplies in the back, not SBB bricks), and it has an internal DWZZB....
In other words, the port on the back of the enclosure is SCSI-diff, but
the host port on the controller, as well as the 2 disk channels are
single-ended. I was even contemplating pulling the DWZZB if I hadn't
found a PCI SCSI-diff card.
