A wall structure includes mounting brackets for server components to be mounted to the wall structure. Different server components are coupled together via one or more data communication coupling devices, such as cables, to form a functional server. The data communication coupling devices and the server components are configured to allow the server components to be coupled and decoupled from one another to form functional servers having various configurations. In some embodiments, the server components and data communication coupling devices are accessible via an aisle adjacent to the wall structure and the server components are hot-swappable so that server components can be added to or removed from a functional server while other server components included in the functional server remain in operation.
