Hi guys, I asked a friend of mine to help me out with my english, so you could understand me better.
First of all, thanks for your solutions, my friend will try to explain the problem again, so there is no misunderstanding:
The GFX Card does not fit in the AGP slot on the mainboard as you can see on the pics. I already have the new version of the PCI slot panel for Stacker, but I still won't fit in correctly. I tried to solve the Problem with different GFX Cards and two mainboards, but it still does not work (the mainboard was adjusted correctly).
To bend, screw or tape something to the mainboard or on the case is definitely no option for me. I don't want to lose any warranty, and my water cooling system does not allow me such experiments, neither on the GFX or the mainboard.
Maybe this is an entirely new problem, I hope you can see anything on the new pics (furter range).
