Well I've run into my first big problem. With the 120mm rad on top and it's fan inside the case as well the optical drive cannot slide all the way back with it's cables installed. Don't think a thinner fan would be thin enough (besides the lost performance). Really don't want to the fan outside on top either; not quite sure what to do at this point. Putting the rad on the rear has it's own set of issues due to space and proximity to the board/block as well (but that still may be able to work with some further thought and planning).
Still can get it up and running today though.
