Wow, that's a really neat job you've done! Usually people just saw off the eject button on the PC drive and re-attach it 1cm or so to the side so it fits through the Amiga's hole, but this way looks cool too. By the looks of it, there wouldn't have been much to re-attach the button to if you wanted to fit it through the default hole anyway, so the way you've done it is probably the best.
