I got a new mac pro abot a month ago and haven't upgraded anything on it yet. A few days ago I noticed a red glow coming out if the front that I never saw before. I opened up the side and saw that the light was coming from four tiny lights on the top and bottom ram risers. Is this normal? I don't think the open front of an apple product should be glowing an uneven red. It seems uncharacteristic and succpicious.
