However, the vast majority of PCs out there are not hobbyist builds but Dell/Lenovo/HP/etc. [1] with far fewer possible configurations (and much more testing as a byproduct). I am not saying these machines never have issues, but a high failure rate would not be acceptable to their business customers.
[1] Well, most non-servers are probably laptops today, but the same reasoning applies.
If you value your time a dell laptop with extended warranty and accidental damage where they replace shit and send people out to fix shit is well worth it. It costs but you can be a dumb user and call "IT" when you need a fix and thats a nice feeling IMO!
