A modular stackable hub system that includes at least one stackable hub for communicating any combination of a multiplicity of electrical signals, for example, ISDN modems, port replication, USB to Ethernet, Ethernet switching, direct current, alternating current, routers, KVM switches, cable modem, firewire, DVD drives, CDRW drives, and USB. The stackable hub would include at least one upstream port and at least one downstream port for releasable mounting to other components in the stackable component system, and may include at least one external port and/or at least one bay for receiving a removable module. The upstream port would communicate upstream electrical signals, which may be any combination of the electrical signals, for example, the aforementioned electrical signals, with an upstream component, and may pass these electrical signals on to the downstream port, where a separate downstream component may be connected, and/or the external port. The removable module may, for example, be a surge protector. Consequently, any number of stackable hubs may be stacked together and releasably mounted to and communicating electrical signals with a base unit.
