I need to install a PCIe Firewire card in a new Z240 but cannot for the life of me figure out how to remove the bracket pictured below, which holds in place the Nvidia graphics card....
....but also holds in place the normal PCI retainer clip.
I have searched for instructions on this particular bracket but have found nothing, and have tried gently to move it from various angles but there seems to be no way to pull it out without putting immense pressure on the Nvidia card itself.
In the image below, the button (1) can be pressed down, and it does pull back on the wedge portion (2) which is tucked up behind the rim above the pci openings, but pushing down on the button does not come close to pulling the wedge portion clear.
As shown below, the bracket actually pins the normal PCIe retainer clip in place (1), so there is no way to open the space for a PCI card without getting this bracket off. The bracket also is directly on top of the Nvidia card (2), so if one were to push REALLY hard downward to try to remove the wedge from under the computer case rim where it is being held in place, that force would also go directly onto the top of the graphics card, which seems like a bad idea.
There must be some direction in which one can apply significant pressure to get this bracket off, but I don't want to try and discover it by trial and error, because I don't want to break the Nvidia card. Or maybe there is some simple solution that I am missing.
If anyone can point me to any instructions or info about this apparently new type of pci card retaining bracket, I would be very appreciative.
