Some reasons I stopped using them (all Dell/Sun): - No real apparent advantages - Make it difficult to access the rear of a server once they are racked - Pain to install/remove/move cabling - Capture heat/impede airflow
I'm actually surprised they're still being sold and used. If you do not have cable management in place, a screw placed in the "middle" of your rear rail screws (ie if you are using 1U, the middle of the three screws for each unit) with a piece of velcro works as a simple/cheap replacement. Now I just use them to play robot in the server room when I am hiding from upper management.
