Build Your Own Macintosh and Save a Bundle 1992 : Free Download, Borrow, and Streaming : Internet Archive archive.org

An RGBtoHDMI  can be used to get video from a classic Mac now as a potential option. It would be period correction of course but it’d potentially be a way to use these things.   Cat Mac was the first thing that came to my mind when I saw these on Facebook.  I have a copy of this book but don’t remember seeing MicroMac brand in it.   Might be worth looking at though.

I've sold compact Macs for many years, and I never heard or came across "micromac" cases for SE or SE/30 motherboards. That appears to be what these are: powered cases for the mobos.

I'm not sure how someone found B/W monitors to be driven by these unmodified boards. Either the product includes some video circuits to accommodate more-common monitors; or someone made custom monitors for it. I don't know the product - inspection will be informative. Worst case - use a motherboard-less Mac SE/Plus/SE-30 and drive its monitor.

Web search for "micromac" finds a service company that makes/sells Mac upgrades; not the same company?, no info there. Also a name for a Rasp Pi Pico emulation of the compact Macs.

So it's hard to find information on the prior company & case product. Here's some links:

That time MicroMac Technology took the CAT MAC (Macintosh from a catalog) mainstream!

Discusses the micromac product and a modern 3D printed case equivalent

Search of Mac magazines of the 1989 period may find ads and details.

As far as value. It seems to be an uncommon item (rare is a judgement call). It's a kind of a thing. Those explain the attention and response to "I have a stack of these ..." Simple math tells me total value depends on working condition of the items in it plus physical condition of case plus intangible "gotta have" value.

I myself would find an answer to obtaining a monitor, and of course evaluate working state, before I'd price and offer them. The floppy drives would need servicing for certain. Inspect the power supply and mobos for component damage potential (RIFA caps, state of other caps, battery).
