Relative delivered a custom-built desktop PC that they no longer want. Inside it is the dustiest computer I have seen in decades, with brown dust caked and clogging the vents. I am amazed that all the fans still work. I drained the battery on my handheld blower, and I still have a ways to go. I suspect this was assembled about fifteen years ago (processor is an i3-2100), put into use, and then the case was never opened again.
