In the 30 years I have been dealing with Dell, and many other vendors, the
mantra is always the same. I.e. you may put the foreign components into the
computer your purchase/ lease from us. However, we will not provide support
(i.e. including warranty) for your SYSTEM for problems involving/ caused by
the foreign components you have installed. They will provide support for
the unmodified system.
My comment was just a warning so you do not get burned if something goes
wrong with the modified SYSTEM.
You can believe or ignore other's opinions. The choice is yours.

You do not invalidate your warranty with Dell by placing 1080TI cards in
their workstations. You just don't inherit the Dell warranty onto the 1080TI
cards.
