You also don't need a display monitor connected to the server. After you install Lion Server, you can run the server headless, using the Lion Server administration tools on another Mac on the network.
This section describes the four Macs, starting with Mac mini for lightweight tasks and ending with Xserve for large networks or heavy-duty tasks. If you haven't read how different server tasks affect the hardware, see the section “Criteria for Selecting Server Hardware,”, earlier in this chapter.
