Need suggestions for a pre built

I honestly have always been terrible with pc’s and wasted money thinking I was getting a good deal.

I’m willing to clean, replace parts, etc. I do not want to build one, I don’t have the time nor the ambition.

Im looking for:

Visually stunning and buttery gameplay (120 fps, 4k)

Reliable and lasts forever essentially granted I take care of it, clean, and replace necessary parts when the time comes

You guys know a-lot more than I do and I’d really appreciate the suggestions/help!
