Is it modern times full height (one of today's 5.25" drive bay) or true legacy full height (two)?
Either way, there are standard SCSI storage enclosures of any height (3.5" or 5.25", the latter in one, two, four, eight drive bay versions) everywhere. The internal SCSI cable can be chosen from legacy narrow, UW or LVD.
Sources? I could tell you where to buy them in Germany ...
