I would like some friendly advice here if possible... I've had my Dual 2GHz G5 for about 3 months now (very, very satisfied with my new baby) and although I wouldn't call my house a "high dust environment" I have noticed that my components (motherboard, heat sinks, etc.) are starting to gather some dust. Has anyone used a can of compressed air to keep the inside of their G5 clean? Any caveats that you can think of before I do so? The only fan that I plan to remove is the fan assembly that you remove when adding/removing RAM, however if any other parts can be removed and cleaned accordingly I'd appreciate someone pointing them out to me!
