Wei Zi Dai er kang Yu Pei

When you buy a branded desktop computer, you are actually buying after-sales and service. It's normal to have other brand accessories in it.

It is equivalent to asking Dell to install a desktop for you and provide after-sales service. Dell can't produce everything without specialization.

For example, aliens should know that the motherboard of Dell's top-end machine is hired by MSI, but MSI is one of the top five motherboard manufacturers in the world, and the accessories in other places may be of other brands, but the quality can be assured. Dell will definitely not choose junk accessories to smash its signboard.
