dunno about ctc but that's quite different to the one for my flashforge. you'd have to move the usb.
Mind you the advantage of a plywood case is that it's real easy to cut new holes :-)

No idea how he did it but, my mate moved the on/off switch to the front of my machine (I cut the hole and had a spare switch - he wired it all up)
And that's probably the best mod you can do :-)

So while you're messing about - stick the switch on the front.
Looks like you'd just need to cut the existing connections solder some wires to them and jusr run those round to the front of the machine.
