Thank you for sharing case schematics. I’ve printed your enclosure. But very tough to fit SSD in that case. Power cable barely fits and SATA couldn’t fit at all. Also, there are no space below board for heatsinks.
Can you make another version with more space under board and taller to accommodate SSD cables? 5 mm below and 40 mm for top should be enough.
With taller height you can put more common and silent 40mm fan.
