Indeed, THE MOST DEVIOUS case design I've seen, and I can usually figure out how to take most anything apart (of course getting it back together is another matter). I would just add that if the macine is years old, the side rails will be VERY stubborn, so if you spray a small amount of silicon lubricant (like Armorall) into the track this will help. I got mine free by first doing this, then grabbing the track firmly with a good pair od needle nose pliers, and pulling while placing both feet against the body of the machine.
Also, when separating the two halves, be carefuk of the bottoom piece, as there are twi small plastic tabs that secure it in place at the front of the machine. If you separate it from the rear first, and then pull the bottom piece back at an angle you can avoid damage to the tabs.
Anyway, hats off to Steve for solving this puzzle!!
