Hi,
Once when I bought my first Amiga 1200 from someone selling it on ebay, I received a computer so full of dust that it took me almost an hour to vacuum out all of it. Then to top it off the PPC card didn't even work, it was fried probably from all the dust, I mean it was so dusty that at first the fan didn't even work, while I was vacuuming out the fan I accidentally knocked it off the board, but even after it was clean it still didn't work.
let me tell you some people, the only good thing was that he took it back and gave me my money back.
