First computer is coming in in a few days (3400c), which I will use as the front lcd since its 12.1 inches, still looking around for some other ones to use, have a 540c laying around but want both sides to match so I need another.

Regarding using the 540c, correct me if I'm wrong but the only way to power on is to use the keyboard right? I know I can use an ADB keyboard, but thats a hassle to have to plug in and out etc. Anyone know of how to rig it so I can use just a straight up power button, maybe even a single power button rigged to boot all three?

Also I've already checked the one apple repair store around here for more laptops, but they didn't have any. Anyone have an old one or two I could buy on the cheap off of you? or where to get some? Thanks.
