PS3 Dust Problems

[Mint]

My house is just the type of house that goes from shiny clean to dusty in a matter of hours so my PS3 does take a lot of punishment with dust, The dust is what finishes of all my Playstations, I had 2 PS1's, 3 PS2's and I'm on my second PS3 (d/w it has the 3 year insurance thingy :P) so I desperatly need a way of either stopping the dust getting in without blocking the fans or a way of getting the dust out in time. Is there anyone else that has this problem and has a remadee?

Thanks, I will +rep you with my amazing 2 rep points. :P
