Manufacturers of component workstations?

Question

Iron

How can I find out the manufacturer of component workstations, in particular, Dell Precision? Who is the official manufacturer of the motherboard, memory and hard drives?
I purchased a workstation, at my request it was customized, but the feeling that the components were replaced with cheaper and unknown analogues does not disappear.

Answer 1

Not all components are manufactured by Dell, for example, memory and hard drives may be from other vendors, but the part number warranty stickers on them may be from Dell.
There are a couple of ways to check:
1. Open the case and look at the markings and stickers on the printed circuit boards.
2. Use a PC configuration software such as AIDA64.
The first way is more correct.
