At this moment the room is around 27C and the various computers show around 50C core temperatures. It typically isn't the cores that fail, though, it's more often the electrolytic capacitors in the supply lines.
Yeah, capacitor failure is always the most common component to go. I typically use caps rated for at least 100ºC whenever I build something, but when repairing I usually find caps rated for only 85º. Important to note that those are upper limits, not necessarily where they like to hang out 24/7.

Has it been the computer itself dying on you, or the (likely external) power supply? I'd imagine the caps in the computer would last much longer than in the PSU given the lack of airflow inside your typical laptop-style power supply for most mini computers.
