hmm... juz read through the forum and i found that ianho said that negative pressure in the case is good because it will drag more air from the atmosphere into the casing.. like physics, air flows from high pressure region to lower pressure region.. do correct me if i am wrong.. I did some cable management.. (I am a noob) but the result is quite impressing..
