Easy Access PC Cases?

swight1701 asks: "I remember seeing the MAC G4 case open for the first time and it was like a ray of light dropped down from above, and the Case was good. This has to have been the easiest access case in history, to be able to flip down the motherboard without removing any card from your PCI slots, genius. So why is it, like most of Apple's more frivilous case designs , and colors, was it not copied by other case manufacturers? If anyone HAS seen this, or know the reason why it wasn't, please tell us all!"
