you need to get a great case mate not good but GREAT.
i have 6 gaming pc's in my house two retired as media servers hooked up to my flat screens. i use only 2 cases for all of them and i havent found a case that can run as cool as these do yet for the price.
my rig case*** Antec DF-85

others in my house use*** Coolermaster 932

both are super quiet and run everything cool
my servers on my drilling rigs run like this and they are in extreme heat and dirt dust 24/7 Front sucks in cool air, top blows out heat
rear blows out heat, side blows out as well. in front of the front fans inside the case i have another blowing right onto the vid cards and mob. works perfectly!!!
