Large-scale science instruments, such as the LHC and recent distributed radio telescopes such as LOFAR, show that we are in an era of data-intensive scientific discovery. All of these instruments rely critically on significant eScience resources, both hardware and software, to do science. Considering limited science budgets, and the small fraction of these that can be dedicated to compute hardware and software, there is a strong and obvious desire for low-cost computing. However, optimizing for cost is only half of the equation, the value potential over the lifetime of the instrument should also be taken into account. Using a tangible example, compute hardware, we introduce a conceptual model to approximate the lifetime relative science merit of such a system. With a number of case studies, focused on eScience applications in radio astronomy past, present and future, we show that the hardware-based analysis can be applied more broadly. While the introduced model is not intended to result in a numeric value for merit, it does enumerate some components that define this metric.
