You can also use a smartstrip, which is what I use. I have an arcade button wired to the power swtich on the computer, when the computers on, everythings on, when I turn the computer off, everything turns off (by everything I mean monitor, speakers, marquee light, etc.). Search the main forum for smartstrip if you want more info on it. I tried searching the wiki, but I couldn't find anything on it, seems like there should be a chapter on power since it comes up often.
