It's been about 2 years since I bought my DG-87 and I'm pleased to report that it's still 100% functional.  Overall I've been extremely happy with it!  Personally, I tend to replace my computers every 4 years so at this point I can consider my DG-87 build middle-aged.  It's probably a good time to perform maintenance.  I'm going to open it up, remove the dust from everything, clean the screens, and clean the fans.  

What I'd like to know is:  Are there any other specific maintenance tasks that I should be performing?



P.S. The thing that initially prompted me to do this was: I heard a fluttering fan noise coming from my computer.  I assumed it was a case fan, but upon further investigation I found out it was coming from my cpu aio water cooler's radiator fan.  I simply tapped it, and it stopped making noise heh.
