Caps: the problem wasn't size or heat. Industrial espionage led to a new electrolyte formula being extracted from a Japanese company and ending up spread around some Taiwanese manufacturers. Unfortunately for all involved (including consumers), they didn't nick the market-ready version. So a few years back, lots of motherboards started failing when they were around 3 years old. Suddenly, there was a rash of cap replacement kits for various PCs available, so it wasn't a hard job.
And that's why Taiwanese motherboard manufacturers still plaster "caps made in Japan" all over their boxes.
