LED pins won't fit. Is there any other way?

I have leds (power, hdd) that won't fit the headers in the motherboard. Is there a way around this?

I have mistaken the computer for being off several times already. The sound is also out of the question with the computer beside a louder computer.

Won't fit, is the case from a brand name PC (IBM, Dell, etc.)? And what motherboard is it? Best option is to get hands on old case rip out LEDs and hot glue gun into your current case. Else you could splice wires, but I am sceptic on splice because is weird the connectors not standard and it could be possible those are not typical case LEDs (they may not work on your current board, not all LEDs the same). Could hack up a CD audio cable (or LED/Switch wires from old case) to get the wires/connectors to splice onto current LEDs.

Fixed already. Thanks for the reply. I removed the pins and made them connect to the ones that require pins in the header.
