I don't think that the stock 5170 ever had a case
lock. You might
have one with a gray trim plate on the back covering up all the
screws, but you just pry that gently off. That lock in the front of
the machine is for locking out the keyboard. Once you've got the
system open, just disconnect the leads that go to the motherboard and
you're in business.
If you have some aftermarket lock, drill the bugger out with a nice
tough cobalt drill bit.
I HAVE seen stock 5170s with a cam on the lock.
But, I can't say whether they all had a cam, since who the hell would LOCK
it??
The case MIGHT have enough flex to get it open once the screws are out
with minimal damage.
Once it is open, take out the screw on the back of the cam lock, and flip
the cam over, so that neither of its two positions engages the strike.
