Can not remove my GTX 970 from case.

[SLT16]

Hello. I have a Lenovo Y700 DESKTOP. I am having trouble removing the gpu from the back of the case. I have unlocked the PCIE lock and done everything else. Instructions for my desktop state that the unlock pin at the back of the case needs to be turned 90 degrees anti clockwise, and then pulled out. I do not know how to do this, as it seems impossible to do so. I will attach pictures of the unlock pin at the back of the case, as well as the instruction manual for the removal of my GPU in my computer model. Here are the pictures of the unlock pin, it is circled in red:

There are a couple of pictures, just scroll through them.

And you can find the GPU removal instructions on this link. There is a directory where it is. It is on page number 25.

Thanks in advance.

According to manual and pictures...
turn the black knob counter clock wise (left) 90 degrees, then you need to presumably pull it out (towards the GPU) and out of the hole it sits at. (hole is visible from the back, it's a long cut line)
You might need to undo both of them (pics show 2 black knobs)
Then do the step 2, which is marked in manual as 1, go figure 😛
"Open the graphic card latches as shown."

After that, the horizontal bar that kind of locks PCI-E cards in place, should be out of way and you should be able to take the GPU out.

If you look at this picture: http://s1253.photobucket.com/user/SLT16/media/2_zps9kpuviqk.png.html?o=2

Which nob do i turn 90 degrees anti clockwise? The small one on the right, or the big one on the left? The thing is, you cant really turn it, as it is fixed in place, and it can only be moved left and right a little bit.

Thanks.

the right side of it should be the "handle" that you turn by pulling it a tiny bit towards the GPU and lifting up and left.
The flat part with arrows is the axis, you can see how it is attached to the case from the 1st links 3rd picture.
Once you have turned it 90 degrees, it should unattach itself from the case.

Repeat for the 2nd such holder to allow for removal of that horizontal bar.

Thank you so much! This really helped me.
