Please Don't Tell Me Yours Looks Like This?

[polldaddy poll="5523016"]

Myself, I built a desktop a while back and I probably dust it once a year, but also do a mild cleaning whenever I upgrade a part. Usually just a simple wipedown and a couple of blasts from the ol' air canister and I call it good. What about you guys? Any special tips you use for getting rid of the gunk?

(bonus points if you post your own rig)
