cdplayer, no problem on the links.
But, it's not that hard to install. The hardest part is having to take the motherboard out to put the back plate on. I did it alone in about 15-20mins. From complete removal of my motherbaord to power back up.
Remember, it will take some force to get the retaining clip in place all the way, but its not that bad.
edit* and they have no leds not legs...
