Has anyone ever reversed the fans on the top of their case so that they pull air in. Just like what the silverstone ft01 does but only on a different case. The reason I'm asking is the I'm thinking about buying a lian li pc p50 in the near future and since it only has one 120mm intake fan, I was thinking that I could get round this by making the two fans on the roof of the case pull cold air to create positive air pressure. What do you think?
