You Have Tons of choices, I have Coolermasters HAF 922 Mid tower,But its more like a full tower with 5 optical bays, a 200mm front 900rpm silent intake fan along with a 200mm top mounted exhaust i moved to the side as a intake to blow on my sli 560s. It also is sporting a bottom 120mm fan that goes in front of the psu, Then i have a antec 620 water AIO system with push pull 120mm fans hooked to the back of the as exhaust. The top i left open with no fans at all, But it will hold a h100 easily with push pull setup.
Here is the link to the HAFx a sweet case under 200$ http://www.newegg.com/Product/Product.a ... 6811119225
here is the CM stryker case http://www.newegg.com/Product/Product.a ... 6811119260
I love the HAF cases the 922, and the932+ HAFx those are the big mother fu*&^%rs.\ Plus they are so QUIET and so much cooling, They use about a 1/4 inch Honey comb design that allows airflow much better then regular holes for the fans. But if you have pets and smoke like me plan on cleaning it out every 3 months or so for lack of air filters
The Cosmos 2 case is awesome but well over 200$, You cannot go wrong with a 932 or 942/HAFx case
There is a soft spot in my heart for Corsairs Vengence C70 Military olive drab green case.....has that ammo box look along with safety covers on the power/reset switches like arming switches for weapons But only space for 3 optical bays, But i know it can hold a H100 also in the roof. I am a WWII fanatic.....if that case was out when i built my 2600k rig it would be holding my hardware right now
