How to open a 17bii+ Silver?

[jebem]

Halo, Walter,

I'm still curious like a cat

Are those two screws in the back cover under the feet?

EDIT:
OK, I found plenty of back side pictures on TAS.

- So, concerning the fixing screws, it looks like the HP-35S in the back, meaning it should have 4 screws.
Two at the top under the feet or under the battery cover, and another two screws under the bottom rubber strip acting as a large foot.

And because it is using screws, it is reasonable to assume that they are fixing the two halves of the case.
Just reasoning and guessing.

- Concerning the front and back cover separation, it looks to me very similar to the HP-20B and HP-30B casing.
Maybe you could try to use the same technique used to open a HP-30B on the 17BII+?
In this case, no prying tools, just bare hands, and see if it opens a little between the metal face plate and the surrounding plastic.
What looks like just a metal face plate can be in fact the front cover, like on the 20B and 30B series.
