That would be cool. I am a little OCD when it comes to monitoring. I can be perfectly patient with a slow computer as long as I know why that machine is slow. But if a computer goes slow on me and does not offer me any way to find out why it is so slow, that drives me mad.

So if the lighting in the PC reflected the components busy-ness, that would be really cool. "Why is my PC so slow today?" - "Aaah, the hard drive is shining white - I/O overload!"

Anyway, my PC has a window-less case, so all that beauty would be lost like tears in the rain...
