Hi, I have a Zalman TNN500AF case and now I bought a 9800GT gpu. The special GPU heatsink that comes with the case does not support the 9800gt heatsink mounting holes. I need to make a retention mechanism to allow me to use my case's heatsink. I can't find any schematics with the precise measurements of this 9800GT/8800GT board. Do you know where to find these "blueprints"? Thanks, Djizasse
