Those switches are actually universal. They have a nice push clicky sound and they're supposidely supposed to ward off thieves or something. I don't know.
I wouldn't mind soldering a new LED on there but seeing as that would be my first soldering project I'm too scared I'd mess something up. By using the above switch I can just cut a 22mm hole, get a harness for the switch and have this power/reset my computer but that leaves the two power/and reset buttons on the front of the case doing nothing.
you could just use the holes from the existing power and reset. Even if you just make a plate to mount the switches, and then cut out the area around the power/reset to house the anti vandal amulets. Simples.
