> Every few months, I'll screw something up and prevent the server from booting or joining the network, effectively locking me out of the machine. To get things running again, I have to disconnect everything, drag the server over to my desk, and juggle cables around to connect the server to the keyboard and monitor at my desktop.
It's worth a couple hundred extra dollars to get a server motherboard with a management port. Just open a web browser to the management IP and it has a KVM.
All my newer servers use server motherboards. The older ones before I learned, always take extra effort.
