Shows 2U in order to fit 32 drives, but hopefully you can find a 2U slot for this absolute monster of a storage box if you have that need.

This one is 1U and supports dual socket CPU and 6 TB RAM:

I've never done procurement so can't really speak to recommendations. I just see that the products apparently exist.

There's also 32 drive 1U JBOF enclosures for more expansion:
