There is no "one to one" relationship between "form" and "function" when it comes to computer components. Parts having markedly different physical configurations may achieve a given ?function?. This poses compatibility problems when damaged systems are to be repaired or replacement components must be integrated with existing equipment

A casually selected replacement motherboard, for example, may not be able to accommodate an insured’s existing ram modules, power supply, expansion cards or even the CPU. This can set in motion a cascade of unwarranted upgrades that exceed inadvertent betterment. In some instances, the need to replace undamaged parts to meet “form factor” requirements represents a form of consequential loss.

Since this is a common strategy in leveraging unnecessary upgrades, the insurer should ensure that the supplier (1) understands the concept of indemnification and (2) selects product options that minimize cost and inadvertent betterment.
