Hi Reid, I'm assuming that you only have a screen on when you need it (I use CRTs, no flat panels yet). Look at if you really need two computers on 24/7. FYI my box has internal temp = ambient (22 C) and CPU runs at 40 C. I would suggest poking around in your boxes finding out what specfically in them is using the power. Hook an ampmeter (or better yet RMS watt meter but buying one would probably buy you a few years of the hydro you may save by the exercise) to the AC to your computers. With them shut down, disconnect everyting but the main board and CPU fan (leave box open). Power that on and you'll see the power used by the MB/CPU, turn of before POST finishes. Then make up a power adapter to let you check the current going to each of the drives. In short, tally everything up and see what could be reduced and don't assume that the biggest power hog is the CPU. If your CPU is a big hog, re-evaluate if you need such a powerfull CPU and consider downgrading to a lower-power unit, possibly even a mobile one. Consider consolidating so you only need one computer on 24/7. Good hunting. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
