First problem is that the PSU at the top is probably not going to receive much fresh air as the majority of air will be exhausted out by the 2 rear fans before reaching the top. This might not be a big problem.Second potential problem is the paths of inflow and exhaust of the display card cannot be separately defined. This problem, IMHO, is a big one. Whether the card is a traditional centrifugal fan type (pic 1) or an axial fan type (pic 2), there will be mixing of fresh intake and warmed exhaust. Re-circulation seems unavoidable.[MEDIA=imgur]a/A2JQsMn[/MEDIA]
