There seems to be a few different expansion chassis boxes released over time with one of them having the card built into the unit itself. I see one of those on Ebay at the moment but it doesn't come with a PCI card for a powermac as well as the cable for connecting the two. I'm not sure how hard it is to find those things.

That is the reason I started http://macos9lives.com/smforum/index.php?topic=2163.0. We need to have an archive of all the expansion chassis available for ours machines.

I asked there all users to make some photos to know what is it a complete system, to be easier to find parts. Lots of powermacs are sold with the cards inside... We need do differentiate them visually, in case we confuse them with SCSI cards (some systems share same conector?)
