There's really not that many cables there, it's just that they are a bit long.
You got that right. I messed up when I ordered my cables from Bluejeans and overcalculated their lengths so I could have plenty of slack when the rack pulls out. I was too lazy to send it all back and reorder so I used it as is.
Also I wasn't aware until last EHX that Middle Atlantic offers a wire management system that goes between the two moment arms of the rack thus I tied down all of my cables to the arms instead.
Could I make this neater, sure. Do I want to disconnect everything to do it, NO WAY! All of my cables are Belden 1694 which are everything but HEMP hardended
Perhaps when its time to upgrade components again, I will redo my wire management, but for now I am loving having my primary theater up and running again!
