Sounds fun.
Even with just an 8-person LAN party, you'd be suprised about the ammount of diversity between the computers there.
There was a high-powered laptop, a huge black PC with loads of flashing lights, a smaller one with a transparent case and many, many more lights. . .
But the rest of them were beige powerboxes like mine. Except my case lid was off, and my CPU fan has really cool green LEDs on it. Made a nice lighting effect underneath the dark computer table I was using.
