Chris! I don't want to alarm you but leaving your computer on all the time has caused your shift key to malfunction!!! :-) Personally I think you are singlehandedly responsible for the Global Warming situation. Next you will be going to 1W single-ended triode amps with huge bulb-like glowing tubes! Did you put green felt-pen on the edge of you cd's? Ha! The ones I fell for where: 1) loudspeaker cables effect the sound. 2) you can hear the difference between turntables. Both of these (as far as I'm concerned) are true :-) I still have LP's. So to get serious, although amplifiers are analogue circuits, the semiconductors are still made the same way. They do tend to have huge bulk capacitors which maybe better left turned on, but I think it's all hooeey. I'd advise you to swap out that 40Gb for something more modern, or at least get an external firewire drive and makes backups. Use Carbon Copy Cloner. CRT monitors are big bulbs, they need to be in standby. LCD monitors also have a lamp so should be in standby. As I said before, if you are really into the idea of keeping you Mac going, consider buying a spare power supply before they are all gone to the landfill. It's the part that's most likely to go bad.
