Eventually yes. Unless (or even if in some cases) you've got battery backed RAID, you could risk some serious data loss. Journaled file systems help a tad, but not by much. You may walk away upon reboot with fsck recovering the journal on the good side to some serious data corruption (flat file DB server mid transaction when you powered off). If you value the data, it's worth your time to go to the console and do a proper shutdown (or heck, Ctrl+Alt+Del, then pull the plug during post after it reboots). Processes are given the chance to shut down and disks can cleanly sync (commit) and unmount. Gone are the days of DOS where you can just turn it off when finished.
