^ Says PCI-E in his post.
I think the 4670 would be a good choice.
Well shame on me for not reading the post carefully enough!
With the psu, I think a vga card that is powered entirely by the pci-e slot is the best that can be used. A 4670 is probably it.
With a fanless card, the case cooling needs to be better, and that can be noisy.
Instead, I would suggest a card with a good dual slot cooler that can send the hot air out of the case quickly, like the hightech 4670:http://www.newegg.com/Product/Product.aspx?Item=N82E16814161251
