>> English speakers do not think of it this way

It worth to say, that "полукоробочный" is non-typical for Russian ear too :) Just another marketing mumbo-jumbo

solution ("They came and offered us what was essentially an off-the-shelf solution"). "Off-the-shelf" is routinely used when speaking of software products. The reason you don't see the "semi" part is because (duh!), perceptually, English speakers do not think of it this way. Take your pick of other modifiers instead - essentially, for all intents and purposes, or whatever else may fit in your particular situation. The "natural" translation here will absolutely need to be contextual. I don't think there's a single one size fits all term to describe this.
