Usually and normally strip of LEDs are covered with plastic.
Plastic as you may know is a bad conductor of electricity.
So in this case you avoid 90% the chance of contact.
Though if the strip leds is touching the motherboard and your system,especially your motherboard is overheating then is risky.
If the strip of LEDs is not touching the motherboard,then its fine.
Can you please post few photos for us here?
