If you mean by a "real case" you have to towerize your A1200: no, not so.
The Blizzard SCSI-option (which can be fitted to the Blizzard 1230-IV and the Blizzard 1260) has a cable and connector which fits nicely in the expansion bay on the rear of your A1200 just below the floppydrive. You can connect any external SCSI-housing to to it, as long as you use the right cable (25 pins). I use a SCSI-tower with four 5.25" drivebays, containing a CD-ROM drive, a CD-ROM burner, a DDS1 tapestreamer and a SQ5110 removable. Looks nice and works like a charm: fast and reliable.
And the SCSI-cable is just a bog-standard external cable, not the internal flatcable type... I don't like the idea of flatcables pouring out of my computer, whether it be my Amiga or any of my other machines...
