i do not have case.. trying to piece together the build before I buy because I love the Dell warranties but i clearly want a top tier gaming pc and aliewnare is kind of lagging so im willing to spend more money for warranty and just piece together different options as long as i know im not wasting money.

Well you are going to be forced to select a GPU from Dell if you get a prebuilt through them I would imagine (maybe not). It's possible they have a 3090ti option already though I would have to look at the configurator.

Reading up on it. It seems length won't be a problem though you would have to remove the front case fan shroud to do so.

There is also the question of whether whatever PSU you get can output the proper power.
