Could a solution be
simply to miss out the hardboard backing board and cut notches in the
side-walls of the base units to accommodate the pipes? Presumably the
backing board is there to give rigidity rather than load-bearing
strength so perhaps I could use some angle brackets instead in order
to give the base units rigidity?

Or put in a new backing board. Fix some timber strips to the bottom & sides
of the base unit & screw the hardboard on. Hides the pipes but easily
removed for access.



Or just cut the existing one down so that it fits the cabinet rather
than the grooves.
I wouldn't worry too much about the rigidity. Presumably it'll be bolted
to adjoining cabinets and, once the whole thing is screwed to the wall,
it isn't going to move. I think the backing board function is cosmetic
rather than structural
