Looking for opinions on controller box

  
This is my first time building something like this cnc plasma table so looking for opinions on what I can improve before wiring everything.
7I96S
THCAD2
24v 16Amp psu
5v 4 amp psu
dm556 drivers (x, y1, y2, z, a)
5v relays for arc and torch control
8 opto isolators for limit switches (2 x, 2 y1, 2 y2, z, z touch)
e stop
If you room for improvement please chime in and let me know before I attempt to not make a rats nest of wires. 

Looks like its going to be a tidy control box. If it were my build I would put the 7I96S closer to the drives to shorten all the drive wiring, keep the THCAD2 and relays close to the 7I96S for the same reason.

Unfortunately I have to keep the card and power on that side so I can get to Ethernet, on/off switch and estop. The way the table is set up I can only get to that side of the control box when in use.

 On one of my builds I used a pass through ethernet port mounted on the panel to use a small ethernet cable to connect to my 7i76e. Its hard when you have limited access but I overcame the problem with a short ethernet cable inside the box.
