CPU COOLER and CASE Questions

Greetings!

I have the following system specs and want to find a good cpu cooler and case. i want to spend about $100 on the case and $100 on the cooler. What are your thoughts on the CORSAIR Cooling Hydro Series. Keep in mind i just want something nice and cool and i DO NOT plan on Overclocking.

For whatever reason i have my heart set on this CORSAIR Cooling Hydro Series. As far as a case goes. Since i have video cards in Crossfire i find that the Mid tower isnt cutting. I want a case that will also keep things nice and cool.

I am a hardcore gamer, WoW, BF, CoD etc... so i tax a system pretty hard. I am not against a MID tower again, but would prefer a FULL, is i have to spend a little more then i can. OH and what are you takes on upgrading from DDR2 to DDR3 RAM? Is it worth it???
