I have a couple PCI and PCI-e cards in this box, and anytime I roll it out 
for cleaning, the last thing I do is make sure the end of the card opposite 
the back panel is firmly seated, they can come unplugged at the drop of a 
very small paper hat.  Note that if your box also has an AGP slot for the 
video card, it also has a lock to hold the card in, so the people building 
this stuff know it can be a problem, but they sure didn't do much for it.
