Not bad! Yeah, there's a few things I'd do a little differently, but otherwise I can see what you seem to be aiming for here, and it looks good. The use of the 1U rows does a nice job of splitting up the cabs, but you could also side-by-side the first and second towers and fill with blanks where there's not anything. I'd go more into the architecture of the modules themselves, but that would be sort of OT for this topic.
