Amazon has a 5 drive rack for $25.

You can also get dual-drive USB adapters for $20.

You can buy a server for $700 or so that has 36 sata bays, ports, and PSU for all of it. I have two in my house. They are loud AF.

That probably is the real problem. Although you could plop them in some separated utility space like a garage.

Define 7 has 14 drive bays.

And the crazy thing is it's not even designed specifically for storage, it just kind of has that space. Good for big GPUs. I have a define 7 for my gaming pc with 0 HDDs installed (M.2 only)! It's a great case anyhow.

I very nearly bought a second one to replace an actual designed-for-NAS case which only has room for 8 HDD; the only reason I didn't is because that older Fractal Design case still works fine. It lives in the living room in the open without shame, and the Design 7 would look even better.
