Is ASUS P5B Deluxe Suitable for a 8800gtx?

[mrchu]

I've specced a system at around 1200, with the ASUS P5B Deluxe motherboard...I'd like to know if an 8800gtx would be compatible?

Also would it all fit ok in a SilverStone TJ05S & SECC Body case? (additionally would this fit a second 8800gtx in later down the line?)

thanks for reading!
