I noticed my Gen 2's front part had a ton of dust in it, I had cleaned it before but this time I can't seem to get the dust out. On what I am guessing is the intake fan there is a lot of dust inside the part where the Dell shiny badge is, on the newer systems it has a light behind it, but I don't know if there is a way to take this thing off to get at the grill behind it, I have tried blowing compressed air but it doesn't seem to be helping, even blowing it out from the inside. It looks like it is held on by 3 brackets. Any ideas?

Any tips on how everyone else cleans their system?
