I would prefer the panels without support if I just have to fill up some gaps in the rack.
If you like to use it for a module, choose the one with support. These are more rigid. If you need more space for your sockets, potentiometers and switches, choose the 0mm support, which is directly on the edge…
Have fun! :-)
And always: I am up for your suggestions and learning. Thank you!
