It looks to me like there are too many differences in the chassis between the integrated and 7800go systems.
You would need to:
1. Cut out the standoffs on the left side for the second heat pipe.
2. Remove the connector from the systemboard.
3. Add posts for card to mount.
4. Make a cooling vent in the right side of the chassis for the right hand heat pipe.
5. The final and hardest part, install a fan to cool the right hand heat pipe for the 7800 card.
The easiest thing to do is return system and order one with the 7800go from Dell.
Returning the system to Dell costs me 155,- Euro or $180,- just for admin and transport.
The system with a Go 7800 is 350,- Euro or $420,- more expensive and on top of that I have to pay 75,- Euro or $90,- shipping costs.
So in total it will cost me $690,-, not exactly peanuts.
To come to the above points:
1. the Go 7800 has no second heatpipe, I do not understand your point. Maybe you are looking at the 7800GTX.
2. Yes, will not be too difficult.
3. Yes, very easy to do. To prevent all problems, 2 nylon bushes are prefered, the other two are already on the MOBO.
4. I do not understand this point. All the cooling vents are there.
5. How difficult can it be to find a fan. I prefer a fan from Dell, but in case they do not supply, there are dozens of fans in the normal trading channels.
