I imagine it will be a set of components that valve will sell pre-completed, or the user will be able to create their own. It could come in minimum, recommended, and max, and the developers would have these basic devices to aim for. The user can upgrade, but it will lead to a small risk on their behalf. If it screws up, they can just put the original components back.
