@X-ray
Yes, I've seen your great photos and enjoyed your all X-rayed pictures ;-) (BTW., photo library is one of the areas of amiga.org I visit most). I also happened to find info it was Enlight case - but I could not find anywhere Enlight cases either. I guess if they are sold online on some auction sites, they are just sold as regular PC-AT case, without info it is enlight "a4000t compatibile", which makes them hard to find via text searchers like google.
Thanks for info about your thread on A4000T - I did not read it before, it was a good reading!
