I still can't understand the need for additional breakers or fuses in the box when the chassis power connectors have fuses built in.

Ok Ill explain. So your Incoming Chasis power has you call it is providing power to the drives which all pull a certain amount of current. Lets say 4A each then you have other items possibly pulling off it taking few amps more so your Incoming suppy needs to be fuse rated to handle all this load plus a little spare so it will probably have 13A fuse.
Now what happens if say one motors blows up and shorts out.? Then drive will Pump current to that motor upto the Max the PSU can provide or until the fuse blows which will be much more than 13A. Now the drive is only rated upto 7A so it goes up in flames.!!! . . . Well not really but it does release the Magic smoke and your out of Pocket £50 just because you didn't fit a 50P fuse.. .

I will help you to do this correctly but I'm a little busy just now but I will come back with a Diagram to help.

Edit: Give me a list of everything your putting in the Case.

Regards Space then yes it's mostly heat related so if your sure you can remove the heat correctly then fine but just because he's not had problems doesn't mean you won't. Electrical components need a certain amount of air flow to cool correctly and any restrictions on cooling will have an affect long term. Or on performance.!!
