how would you recommend lighting this little logo in the GPU without spilling too much light throughout the GPU?

Thanks for any input.
A couple of LED's, small ones. You might even be able to solder then to the GPU's power ports and get power to then that way. Also your case has too much white i dont like it. But i love the NZXT sentry, thats the one i have.

i was going to do it all brown, but i didn't think you'd like that either.

i'm just being a smartass.

...and can anyone else confirm the suggestion to borrow power from the GPU power port to light one led?

I'd tap into the 12v on the card, under the GPU shroud. The PCB pins on the power connector are usually open, so you could solder a resistor straight onto a 12v pin, then add the LED onto that & back to a ground pin. Nice and easy, and no extra wires. Then just tape or similar to stop the light bleed.

get ready to laugh...what's a resistor? i've only ever bought led kits...never hooked one up myself before. also, are standard HDD leds and PWR leds 5mm, or 8mm?

your white LED will run on about 3.5-4 volts, but the 12V line is at, well 12V. You need the resistor to drop the extra voltage down so your LED won't burn out. You can pick up a suitable resistor from RadioShack or similar for a few cents - but you need your LED first to determine the value you need.

It doesn't matter what size the LED is, because the all run off the same voltage. Larger LEDs tend to be brighter and use more current, but this isn't always the case. Find an LED you can get to fit, then work out what you need to hook it up.

+Rep...sounds like the way to go. ill have to remove the shroud again of course, but are the 12v and ground easy to spot, or do they all look the same? i guess it depends on the mfg.

the row of pins next to the clip are ground, the other row are +12V.

If you can see the PSU wire colours through your sleeving, the 12V wires will be yellow and the ground wires black.

got it...just sharing with the power led ....the resistor thing confused the heck outta me. the people at radio shack were useless.

Man that is probably one of the sexiest interiors I have ever seen. Looks like it came straight out of a clean room.
