Small Mini-STX (mSTX) chassis with 3.5 inch HDD bay?

[eicar]

Among my home lab plans is an option for a small off-site remote backup server. I would use the following basic components:

• Kontron K3921-N1 Mini-STX (Intel N50, 2C/2T, 6W passive, DC) – https://www.kontron.com/en/products/k3921-n-mstx/p180695
• Kingston 8 GB DDR5 4800 SODIMM non-ECC (KVR48S40BS6-8)
• Seagate IronWolf Pro HDD 22 TB
• USB 2.0 9-pin header to dual Type-A connector splitter cable (for internal Unraid boot drive)

Problem is: I can't seem to find a Mini-STX (mSTX) chassis with an internal 3.5 inch HDD bay. The only ones I could find have one or two 2.5 inch HDD or SSD bay(s), e.g. the ones by Akasa.

Anyone know of such a chassis? (tia!)

The only important thing is that it should be as small as possible. But it needn't be passive; an active chassis would be fine, too, even with more than one fan. (I could just buy a PWM 4-pin splitter cable.)

 

PS: if you find any problems with the above (very basic) build, let me know. 🙏
