You can check out Lian Li's Lancool II Mesh RGB

It already came with 3 RGB Fans, has really good Airflow and well-designed internals.

actually if you do not require the 5.25 slots I personally suggest the following Casing

NZXT H510 - to look clean and chio

BEQUIET purebase 500dx (MESH Chassis) - pretty decent airflow

Lian Li Lancool II MESH - pretty decent airflow
