How do I organise a flush-mounted multimedia switchboard in the loft?

Hi I am looking for some solutions for a multimedia switchboard. It does not have to be strictly a switchboard but something where I can aesthetically place devices such as modem, switch and antenna distributor. I plan to put the cabinet in the wall in the attic so it would be better if it was something flush-mounted. As I wrote, there will be room for these three things, I don't really plan to add anything else. I have the router downstairs in the flat.

A picture of how it currently looks:

Thanks in advance for any suggestions.

Rack cabinets are used professionally for such things.

I just don't want rack cabinets too much because I don't see room for a simple switch and modem, and I don't and won't need such things as patchpanel etc.
This wall is going to be re-plastered so surface mounted will probably actually be better.
Can you recommend anything? I've been looking for such cabinets with shelves but can't find anything....

Check out Pawbolu's boxes for yourself:

Solid plastic, dustproof and deep enough to make some sort of shelf. I sincerely recommend them.
