A bunch of PC manufacturers are being hit with bad capacitors.  (If you slept through high school electronics, capacitors are used to temporarily store electrical charge and regulate voltage — old timers sometimes call them condensers).

CNET has a good picture of the problem:

Swollen capacitors on iMac

You can see the swollen caps in the back.  These things swell and then leak a kind of yellow goo which crusts over, utlimately causing video problems and intermittent system failures.  

Dell has this problem on some Optiplex workstations (incidentally, the very workstation I have in my office).  But they aren’t the only ones.  We’re talking about HP, Apple and apparently others have this issue. 

Unknown is how widespread the problem is.
