Where is the best place to wire up LEDs for a PC case mod?

I am modding a PC case so that it has a side window and LEDs on the inside. Do I wire the LEDs to the power supply, motherboard, or someplace else? And where?

I would use one of the HDD Power connector cables, and cannibalize a cheap Y adaptor, to make the clear panel detachable. The yellow wire provides 12VDC, at fairly high current. The red wire is 5VDC, but it's not advisable to draw a lot of power from that. Each of the black wires is a ground wire. If you use about a 1k-ohm resistor in line with each LED, you'll draw about the right amount of current per LED (close to 10 mA).
