How do you open the case of a PB iXtreme x5620 (m3720)

Hi,
Im trying to open the right panel of the case of my PB desktop PC to insert an adapter card into the PCI slot.
I've looked at the manual and it says you have to remove the screws on the back and press a locking switch to unlock it, but I've looked over and over again around the PC and that switch isn't there!
I've tried removing all the screws except for the ones holding the power supply, but I still can´t manage to get any part of the case off!
Please help me!!

Somtimes the switch is on the front top or bottom (same side as the panel you are removing)

sometimes the 'switch' is just a pressure panel thing too, look for cutouts on the panel edges, it might be hidden on the underneath
