I currenty have a TT S31 Urban Mid ATX case, but the things is that I had to place the fans under the outer cover of the case (the removable top) The radiator+fan wouldnt fit inside the case becase of clearance issues with the dimms.
I'd like to know what cases could house the rad+fans inside of it, without having clearance issues while keeping the Mid-atx size.

But it is a E-ATX D: not Mid-ATX.
Oh well, thanks for taking your time looking for a good case.
Do you know if the rad+fans could fit in a Corsair 550D or Antec P280?
