Ok it wont fit.

I am left with a bitter taste..as if you go an read swiftnets.com and then check the compatibility list one will understand that the GPU block will fir the 8800GTX series without any other attachements needed. On top of that the unit was sold to me by a retailer stating:

"1. Pre-assembled retention mechanism using the four holes surrounding the processor:

All nVidia® GeForce™ series from 6800 and above
All ATI® Radeon™ series from X1300 and above"
