There were several SCSI enclosures that had similar design lines and color
to the GS - or more accurately, the the Mac SE, SE/30. It sounds to me like
you have one of these - what most people call a "zero footprint" drive. It's
meant to sit under a compact Mac like the SE or SE/30. There were dozens if
not hundreds of brands - some matched the design of the Mac more than others
but were all pretty much generic in nature. Apple had it's own line of ZFD's
(20/40/80/160SC), CD and Tape drives in that form factor but they cost a lot
more, hence the popularity of the generics.

Placing the drive on the case, I doubt is helping the GS in any way - the
convection vents are shaped for air flow out, not inward. Whether you set a
drive enclosure or a monitor on the GS case, it's important to leave a gap
and let the convection vents work. The GS monitor ships with a shim to prop
the monitor up - it's not just for obtaining a better viewing angle - it's
also there so the GS can breath.

I stress that the Kensington System Saver is the best practical cooling
option for the GS - and I personally would fall back to an external PC power
supply before I relied on an AE Conserver to cool a loaded GS. All of my
machines are seriously tricked out and practically all my slots have
something installed in them. Anything less than a good fan on them, and they
malfunction.

Thanks for checking that. In replying to you, I've said some things that
weren't directly relevant to you but were for the benefit of anyone else
reading. Just general info/advice.
