Yes. It's this my computer. It does not fit because the back panel does not come out all the way to accommodate the hdmi/tv hook ups on the back of the card. What I can take out only allows for a partial fit. I wish I could explain it better, but I can't take out enough back panel on my PC to make the card fit.
And you won't find a worthwile 1 slot gpu, all the nice ones are 2.
Anyway ; the part with the screwdriver is meant to be taken out, brake away, otherwise you never could use a card.
The small part in between the parts with the screwdriver which can be removed ( the part in the green ) stays there, it shouldn't be in the way of your ports.
Not sure but i think you have to loosen the big part left also, is that a screw just above the word remove in the green cirkle ?
Not sure but it looks a bit the same as mine, i have to loosen the screw and can swing that part out of the way then, place the card and turn that part back and screw it back on.
