So, I rarely burn stuff with my 20" C2D iMac (non AL). But when i do, at full speed, it makes a horrible vibrating noise, like a whirr that I cant stop no matter what. Thankfully, full speed means less than 3minutes of burning, but still... I dont mind it really, but if I try to resell this sometime, its a real downer. My 1yr warranty is up Feb 2nd, 3 days. Should I call apple? What do you think they would even offer to do? There aint no store within 100 miles, nor an authorized repair center within at least 50.
