Looking for a new case.

Hello. I'm not as well informed about cases as I would like to be.. so I decided to look for some help.
I'm looking to buy a new case for my PC. My PC has two ASUS Radeon 6870's crossfired, and a i5 750 overclocked to 3,6 Ghz.

My current case (Antec 902) has quite a lot of fans, all manually controlled. So If I want to play something, I have to reach all the way to the back of the case, just to turn the fans up. So I would like the case to have some sort of automatic fan control.

The case doesn't need to look pretty, nor does it need to have disco lights in it. All I want is some good cooling power, automatically adjusting fans and maybe even some sound insulating.

My budget is about 100€. Although I guess I can save up a bit more if necessary.
