I have just junked one; the long and stiff cables make excellent emitters and it is impossible to make up a neat or tidy system.

Hi,
"long and stiff cables make excellent emitters"
1) Stiffness has no effect on the Aerial action of a cable.
2) Length must be seen in respect to the wavelength of the suspect signal. For most off mains SMPS 50 - 200KHz is the switching frequency so 6 - 1.5Km - next to which all cables attached to an ATX supply are VERY SHORT. Even if we allow the 50th harmonic of 200KHz we are still talking 30m wavelength. I doubt your ATX supply came with 30m cables.
3) In order to emit an electrical field it is recommended not to run any emitting aerial closely parallel with a ground/earth conductor. In most ATX power supplies ground and power cables are bundled together, if not twisted together (which would be better and less stiff BTW). I doubt the one you had was an exception.
4) In order to emit any signal, regardless of conductor length, presence of not of ground/earth conductors and (cough, cough) stiffness, there has to be a signal of appreciable magnitude to start with.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to untolerable pain. Really, what more could we need?
Stiffness and length mean that the loom is a mess in any computer enclosure.
Emitter is a colourful way of describing inter power rail pickup/modulation and is no more than your own colourful exaggerations as illustrated by the nonsense on the website describing the products that you said you designed.
If you have money to burn, try using a modular power supply that has lots of smaller conductors in a flexible ribbon cable format. I've got a bunch of Corsair RM1000's powering some equipment and these are have flexible cables that are very easy to work with. BTW, there are lots of ground wires interleaved between the +12 wires. Need lots of wires to handle 83 amps at 12 volts per power supply.

I have - Superflower fanless. There is now another one with all detachable cables.
The problem with these makes is:
They all use stuff wire looms and there is no way to shorten cables except to cut them.
I am making one up based on a Corsair accessory ATX cable but it is quite a job as all wires are orange.
