If you need to replace the caps anyway, then I think just cutting through the outer PET sleeve should do as chances are it's only the sleeve that's got glued and not the leads or the closing cap. Then you might be able to just pull the inner aluminium can containing the capacitor itself from the sleeve and with the component proper out of the way get rid of any remains from the PCB. NB the originals are just snap-in capacitors AFAIK, e.g. Chemi-Con KMH series (I can't figure that out from your photos and luckily none of my H7878s has failed so far, so I haven't made this a part list for this PSU for myself), still manufactured, so modern replacements should do. With the PCB hole diameter supposed to be 2mm by the manufacturer's spec I wouldn't be bothered with a small lead pitch variation, you can always bend the leads slightly as there's some space between the closing cap and the rim that rests against the PCB. Also I would't be bothered about the LED holder getting damaged; it's a standard piece, available online. I can dig out the part numbers, separate for individual pieces of the holder (you can match different kinds against each other, depending on your needs), if that would help; I ordered a bunch a while ago for my own use.
