I shook my head. "It's a CPU."
She turned on the power. Behind the CPU fan a whold bunch of red, blue and green LEDs flashed on for a second. Then they began to flash in sequence. Red Green Blue Red Green Blue Red Green Blue Red Green Blue Red Green Blue.
I blinked. "What do you think?" she asked me. I blinked again.
"Put the case on for a moment," I said. She put it on and I examined the pc. There were no windows, vents or portals that let the light out. It was, to all appearences, a perfectly normal PC until you removed the case and it was all Red Green Blue Red Green Blue again.
The pointlessness of the mod is utterly breath-taking. It's like taking a bog-standard 1969 Kombi van and chrome plating the air filter. WHY would you spend money on that?
