SilverStone currently has two versions of the Redline RL06 available in two colors (black with red trim and white with silver trim) the standard RL06 one and the RL06 PRO which as stated above is the one we have here with us today. For good or bad don't expect any significant differences between the two versions since they only have one and that's the three 120mm LED fans (red for the black and white for the white) placed behind the fascia.
