Having also worked in IT, I would agree PSUs are usually the first thing to fail.
I would put ports ahead of Video Cards. They rarely fail, but sometimes a pin gets bent or something. Or in Laptops the connection to the external power.
If a hard drive doesn't fail in the first 3 months, they are usually good for years.
And the only memory I have ever had fail was user error - not discharging properly before someone touched it. Now sometimes the heat/cool cycle cause them to get a little lose, but never had one actually fail.
PSU are also one of the few things we didn't even try to fix. We just replaced them.
Note: My 2010 PC is on it's second power supply.
