Lwkl summed it up well. A great example is an HP z laptop - good build quality, sort of the equivalent to an old T series thinkpad.
With two Phillips screwdrivers, you can disassemble and replace most parts within 15m.
When I did this work, the other key thing was OEMs would guarantee image/driver compatibility for 4 years. I don’t think they do that anymore, but the hardware is very stable - consumer PC hardware will often have variance based on cost and supply chain.
Enterprise doesn’t want surprises and cares about total cost. So keeping it boring and predictable rules the day. Depending on scale, repairs are important because at some point it’s much cheaper pay for service by the drink vs warranty.
