My motherboard has useful lights. They illuminate according to the current stage of startup. I think it's CPU, RAM, VGA, and something else I don't remember. Got a RAM problem preventing boot? It hangs with RAM lit up. This is infinitely more useful than the arbitrary undocumented 2-digit BIOS codes that it also has.
Carter: I've finished comparing Goa'uld control crystals, all that glow is completely unnecessary.
O'Neill: So they added lights inside closed boxes because…?
Teal'c: The Goa'uld have always favoured displays of grandeur over practicality.
O'Neill: Hold on. You're telling me the galaxy's self-proclaimed gods are flying around in gamer motherboards?
Carter: Sir…
Daniel: No, I think Jack's right.
O'Neill: I am?
Daniel: Glowing lights everywhere, gold trim, needlessly dramatic startup sequence. And they definitely treat us as pawns in their games.
Teal'c: Indeed.
