it is an intel case, there's a thread about it here:
The first ATX case?

Thank you!! I was looking for more information, followed the links from the "The first ATX case", now I have photos of the Intel Etended Xpress!

I had this exact case back in the 90s and trying to track it down again. I could of swore it had an Intel part number on it but here it is with a branding of Systium Technologies. Did anyone else, Intel maybe, sell a version of this case?

^^This, and you can still find the Systium product page on Wayback 😀
