I was considering the Antec P180B case but I'm not sure wheather the 8800 GTX fits into that one.
Really appreciate your help.
as long as you remove the top hard drive cage it should fit just fine.
i personally prefer the TJ07 with the optional side window. as for the power supply, use something like this or this if you're looking for something modular. both power supplies have quad 12V rails with 18A each.
