Origin of faulty caps
I heard a different story about the problem. Chinese organised slime bought cheap audio-grade caps on the open market, employed slave labour to replace the labels with fake good-name low-ESR labels. They then sold the relabelled caps back into the market at the (in)appropriate premium price. It was a year or more before they started to fail in service, by which stage the criminals were long gone with their loot, and ~50M motherboards were doomed to die young with brown gunk oozing out of their caps. Also, they always went flakey for weeks or months before they failed completely.
I don't think one can blame manufacturers of boards or systems for the problem if this is the cause. It's how such a problem is handled that's significant. Note the blatant lie "customers' data is not at risk" in the Dell mail. Anything that can cause a computer to crash poses a risk to the data that it is processing, or to the process that it is monitoring.
When I'm asked what I think of a company that's shipped us lots of kit that works perfectly, I say "OK". I don't have what I need to say "Bargepole" or "Brilliant". I get that when something goes wrong, which I assume is inevitable given enough time. A brilliant company accepts responsibility (not the same as blame) and sorts it out, fast. A bad one finds excuse after excuse for doing nothing, or simply fails to answer the phone in any meaningful way (call centre hell or plain no answer). What are these bargepole outfits thinking? That's I'm stupid enough to risk being fooled twice? Or that there are plenty of other suckers out there?
A grenade ... what the Chinese Slime deserve, along with any company that employs people to deny problems instead of fixing them.
