It wasn't just computing equipment. I have hand-repaired a dozen sets of amplifiers and powered studio monitor speakers made between '02 and '06 that just needed $2 worth of caps replaced despite the manufacturer quoting $250+ for authorized repairs.

In about half the cases it was a combined failure of the caps being el-cheapo and also the board design placing them far too close to heat-generating components. Fortunately, it is still cents on the dollar to replace with a higher temp-specced part if you know how to wield an iron.
