If you're going to run your 'puter 24/7, then remember these three letters: U P S. It pays to get a small uninterruptible power supply (they're kind of pricey, but the cheapest ones can go for as little as $50.) You don't need enough battery to last you the next three days, but a small one will keep your machine powered-up just long enough for you to shut it down properly (about 5 minutes or so.) The better personal UPS models have a serial port that you plug into your computer, so that when power goes out, a signal goes out to your machine, and it then automatically shuts down all running processes, then shuts itself down... you don;t even have to be there to see it happen. /P
