A long time ago, I have a hard time to find E-ATX case where you can place MB horizontally (!!!).
Eventually, I found one Thermaltake Core X9
https://www.thermaltake.com/core-x9-snow-edition.htmlMy recent update to AMD Ryzon rise a question where I will put all these and keep existing systems in place as well.
Another case? Ehh, I thought, but limited space a lab not much choice to rid off 'behemoth' and squeeze two new ones in.
Eventually, to my surprise, the case has 2 PSU bays and allows extra space to accommodate another E-ATX board. Relief!

Just a small workaround - aluminium tray with few holes to support MB and still need print/find spacers to level it out.
