any thread on layout inside a case?

Hi,
I am in the process of putting a transmitter inside a 19 inch 1 hu case to go in my studiorack to be abe to send the signal to other rooms. The case i completely made of metal and I thought of getting the signal in and out using d type connectors for audio as well as a bnc one. The transmitter, cheap chinese bh1417 transmitter ic, takes 5V which I thought to deliver using a meanwell psu that delivers 5V and 3 amps which I still have lying around. From what I read this is like the worst option I could choose (I have to say the sound is alright) due to harmonics. I don't know how much of an issue this is when used inside a flat of a densely populted area. I am not living in London anymore so I doubt that here is a team that just deals with this. If there is a chance of me messing up airplane or emergency transmissions, even being inside the flat I would use something else.
I am open for suggestions on alternative options but at the moment I don't have time to etch boards or do any other complex stuff. Doing a kit would be an option or buying the whole thing but I don't want to spend too much.
I was wondering if there is a thread on how to layout the components inside the case to prevent interference etc.
Also when shielding the components to each other will it be fine to use a can I cut, bent and and screw to the baseplate (using dibond as baseplate for easy access and as it is great to work on) and would it be a problem to have some other stuff inside the case (using a cat 6a cable from my dj setup to my audiointerface as it allows to transmit balanced audio and is super cheap, I would like to put the connector that I grab the signals from in there as well and use 2 xlr sockets to get the audio out into my interface instead that shitty little plastic case I did a year ago.
I don't have any experience regarding hf technique. Would it be better to use a higher Voltage PSU and regulators to get the 5V needed?
Thanks for helping
