Atlantean - installing is v. easy.
Basically: Take the front cover off the case, loosen the screws on your drive and slide it back half an inch or so. Snap the cover in place the same way you would snap one of the bay covers in, and then hold it in place with those little black screw replacements that are used on the Lian Li case fans (don't know quite how to describe them, but they are great little things).
Then you just move the drive back forward till pressing the button on the cover will press the button on the drive. Screw into place. Put case front back on. Enjoy
Blooz1 -I'm not sure that these will do the job for you. The only thing breaking the front finish on these is the button. No hole for the light, or for a play button, or for a headphone socket. I can see the light on my drives (only just, and only a tiny bit) because I sit very close to my case (10 inches to a foot) and its at eye level. Since my room is dark (and I often have the light off to cut down on screen reflections) I can see the light through the fold line. If your case isn't near you, you might not be able to see it.
I get home from work in about 2 hours. I'll try to take a few photos to demonstrate it all.
*edit* - They do look great, though!
