Yep, great minds think alike! I use KrudKutter to clean the case and compressed air to blow out dust from everywhere. I use tie wraps to clean and dress up the wiring and replace fans, as needed. When I finish with a PC, it looks and runs like new again. If someone is a smoker, then all bets are off because the tobacco smoke gets gummy, brown crap all over the components and it can't be properly cleaned. I just saw 2 PC's ruined by people smoking in front of them. ebery component was ruined because the comination of dust and stick tobacco residue got on everything. The PC's stunk and I cleaned them (or tried to) in the garage. After I finished, the dog wouldn't even come near me!
