I'm glad to have logged in today. This post inspired me to check the voltage of the front Alien head LED, as my emblem LED was not emitting, and may be the same for the lower grill lights, too.
If you do end up doing a blue LED to your grill definitely post pics of how you did it. I did it with a LED fan but I'm not honestly happy with the way it kind of jams the door and makes it a struggle to open/ close the side panel. I'm also considering doing like an IR LED strip that I can change colors at will.That's a cool idea to have the front alien head-emblem blink as the hard drive is accessed. I really like the blue glow in the front grill, too. I think I'll do that on mine, as well. Thanks much.
