Advice needed for controller box layout

[Bustercnc]

Hi,

Any advice would be greatly appreciated. I have just purchased a little cnc router for PCB work.

I have been trying different layout options while I wait for cables and connectors to turn up

There are three options that I can see and wondered if there are any issues with these, like electrical interference, heat concerns/ventilation or anything I may have missed.

Options 1 and 3 involved mounting the BOB onto acrylic and attaching this to the door panel.

The external case dimensions are 400mm x 300mm x 150mm but the removable steal base panel is 350 x 250 which is what I want to keep all the electrics on for ease of removal. All the connetors wil be mounted on the access panel on the side

Option 1 - and preferred option for me





Option 2





Option 3
