Good input, I stuck the "weak" and "good" in at the last minute, I'll have to go back and fix that.

I added holes all over the place, changed the caps to .1 spacing as those are more common, not to mention smaller footprint. Of course, I did change the LED colors, you were right. I figure the power switch might just be a .1" jumper pair with a jumper on them, that's the simplest case.
