Oh — so... a ferrite bead on the power cable outside the case (I thought on one or more cables inside the case)?
Anyway I ordered two of the ferrite flat cables SA28B0071 @Lugia recommended — looking forward if it suppress a very very high frequency noise coming out of Beads...
This might be solvable with some ferrites. First up, these: https://www.dxengineering.com/parts/dxe-csb31-525-5 These should go on the DC out from the Meanwell brick...open one up, loop the DC out line around it a couple of times right next to the brick, then snap it closed. That'll kill any RF on the DC line before it gets into the cab.

you meant with one of them, wrap all the DC OUTs of the MW supply (-12 / + 12 / COM-GND / +5V)? or each of them?
