Rack chassic for "tower like" eATX motherboard

[dante4]

Good time of day,

I'm thinking about buying AMD Epyc 7551P and GIGABYTE MZ31-AR0 (or supermicro H11SSL-i), but the problem is that I just can't find rack chassic for it.

Since it's more "tower-like" motherboard - i can't find a way to include riser, so I need some kind of 2U or 3U chassic to insert PCIe cards.

Mmaybe someone have experience with building system like this and may provide me with correct direction?

Any 3U chassis will do. One does not need risers for regular 3U or 4U chassis. Supermicro makes plenty or you can get a cheaper generic one off Newegg.
