How to open a vaio all in one

[tpfaff]

So I'm trying to open up a family members vaio all in one. Specifically it is model vgc-js290j. Theres a ton of screw on the back which I managed to unscrew and I can't for the life of me lift the back piece of plastic off. Does anyone have any experience with these?

If it is like anything else, probably just snaps along the edge of the chassis.
You could use a spudger to get into the groove and pry.
