Saw it with Dell Optiplex GX 270 as well. I supported between 50 and 100 of those at some time and we had to swap 30 motherboards in 6 months.
More info used to be available here: https://www.badcaps.net/, haven't verified recently.
One thing I've heard recently though is that Dell still makes batches of bad hardware and their service is stil (or again) bad. In particular a recent xps batch has had a 50% failure rate while Dell support keep blaming the users IIRC. Source: sysadmin friend of mine.
PS: once you get through, their technicians used to be great.
Horrible design, internally anyway. Caps near the power supply or CPU heatsink were prone to failure. At the beginning of my IT career I swapped many of these motherboards. Fortunately the power supply and motherboard were easy to remove and replace.
I think this was a Pentium 4 machine which also was notorious for running hot.
