No experience with it ... it seems a bit out of proportion to the rest of the build, given the specs of your system any decent case will do. I like the P182 because of the looks (P183 is hideous) but it's not very roomy, has no gap to access a cooler backplate and the airflow for the GPU is not ideal. Raven is pretty close to ideal airflow for the GPU ... pity it's so fugly.
Not a big fan of custom fan sizes though ... it's not like you need all that fan power to cool your system, P182 could handle that with 2 120mm system fans running at 600 RPM ... I have a hard time believing you can get those 180mm monsters as quiet regardless of RPM.
