Yes that case is fine. I still recommend the F3 for your HDD, will save you a bit as well. I liked the first set of RAM that you chose with CL7 better. Remember that even though you have a crossfire motherboard, if you use the 500W PSU that comes with the 200, you won't be able to add another 5770 (since you said maybe to crossfire). If you want to drop the crossfire mobo, look at the 785G chipset instead.
So if i don't plan on overclocking or cross fire, would it be wise to change the video card and the mobo.. so right now im looking at
AMD Phenom II X4 955 -$170
SAMSUNG Spinpoint F3 500gb -$54
Sapphire Radeon HD 5850- $300
Sony CD/DVD Writer- $22
window 7 OS- $100
CM 690- $69
Antec Earthwatts 650W - $76
total 791 w/o mobo and ram
can you recommend me a mobo and ram that can go with this rig?
