The case is ultrasonic welding. You can break the weld and take the case apart and then replace the cable, but it will break messily and afterwards you cannot just use superglue to stick it back together.
The iPowerX looks like the case uses screws to close the case, so it should be possible to open up, remove the beastly Chinese blue LED light (its plugged in) and dispose of it in the nearest "sondermuell" bin and then replace the cable.
While it is open, ditching the "FCON" brand solid electrolytic capacitors for Panasonic (ex. Sanyo) Os-Con is definitly worth it and swapping out the generic PSU Capacitors for similar size and same value "ultra low impedance" types (I like the now discontinued Sanyo "deep green" ones).
Beryl, which should be the in input Capacitor (C5) is one of the better China Cap makers, but a MIJ/MIUS Chemicon alternative may perform better. There is a small ceramic cap (103/500V - 10nF) in parallel with it (C7), a relatively large value and size film cap may improve things, 450V DC rating is needed.
Finally, there is a blue capacitor roughly in the middle of the PCB labelled "CY1" right next to the Optocoupler U2 and the power transformer. If the transformer T1 is still wound according to my design, CY1 can be removed. It should be marked 100pF - if so, just pull it out (clip it out) it's not needed at all (long story why it is there and it involved the "C-Word").
With this cap removed and the cap upgrades the "X" might even beat the Aliexpress linear PSU's on mains leakage and overall sound quality.
Please note that this does not mean I endorse the "X", at this price all the improvement I suggest should come ex factory! instead it is basically identical to earlier iPower, with a more fancy case, thinner DC cable and utterly pointless and offensive "Chinese Blue Lights".
And here a track with a bass drum that should have insane "slam"! It's an Oberheim DMX Drum Computer. Razorsharp. Neue Welt Ordnung! Ewige Blumenkraft!

Which ones are the FCON?
The blue or green arrows?
And which ones are the PSU capacitors?
I found the rest you mentioned
