Doubt anyone will have use for it, but here just in case some part of it is useful.

I had a Thermaltake RC3400101A MAX-3543 sitting unused after I upgraded to NVMEs and decided I wanted to put it to good use as a backup server but in NAS style. I found out Pine64's RockPro64 has a PCIe slot which allowed me to use a 10Gtek PCIe 4x SATA controller (https://a.co/d/8O4ulsz) and for that I got a smaller PSU for all that (https://a.co/d/g3ITvI8 ; probably way more than it's needed but these things are cheap enough).

Only missing part was the case. This is what this model is: a OpenSCAD made case with two parts: the main case for the disk enclosure and power supply with space to run all the cables and a top part for the Rockpro64. Now you might find it odd to have designed the Rockpro64 on top instead of being inside the case until you realize it has useful ports on both sides. The Rockpro64 part fits very snug (I didn't even use screws and hot inserts as planned) and 4 tabs secure it on top of the case. Since it's done so the Rockpro64 is upside down, the SATA controller extends inside the case as you can see in one of the pictures. I've used a SATA power plug to provide power for the Rockpro64 and while I could have removed the barrel connector and solder the wires directly, I just decided to bring the cable and connector out. I also opted to not have a power button, instead I used one ATX mobo short and just power on/off using a smart outlet (or pull the cable).

While the Thermaltake enclosure is likely to be very hard to find, it seems they have a similar and more modern version that could be adapted.
