I finally made a decision and went for a Rad 9800 pro while I wait for Socket 939/PCI-E to settle down. I wouldnt mind fitting an Arctic VGA cooler rev 3 to it, as my Shuttle is pretty warm.

Will this fit in a Shuttle? I know someone makes a card with it pre-fitted and I think someone said it would squeeze in.
I've got an SN41G2, and my PCI slot is being used (I dont think that matters?).
Cheers.
