I have seen that but I don't know if it's the same inside, externally it looks a lot different

There we go, I missed it, I didn't think of "rackmount" it was in the schematics library after all

They are quite different in appearance and internally, whether they differ in terms of circuitry, I don't know, maybe a little bit could be a lot.
