The 8800GTS will fit in the Lian Li with no problem, but for the GTX you'd need to take out the hard drive cage.
I have that Lian Li case, and I love it. The only criticism I have with it is that once you get it, you'll be afraid of scratching and denting it. I'm nearly paranoid about that stuff, you just need to be careful with it. There aren't a lot of places you can hid cables, but even with three hard drives, two opticals, and a light controller I'll be removing soon because I don't have lights in it anymore, it's not that bad. Just makes you get inventive
If you like, I can post some pics of it with my hardware inside.
