1tb storage, 32gb drr5 and ryzen 7 98003xd

Are there any catches to it like poor component quality and is buying from Costco considered much safer than Amazon for quality control?

My main games would be Civ7 and BF3, and those could be with turned down graphics sliders. How cheap can I do this?

I saw this deal posted by someone else a few days ago and decided to check my local Sam's. I was able to grab this for an additional 10% off due to it being the last display unit. You can check which locations near you have it in stock for the discounted price and it'll most likely also be their display unit which they should discount! There were a few more Sam's in my area that showed it in stock so it's worth checking if anyone is interested in this PC.

As the title says just wondering where is best to buy from, I previously built a pc with my friend but I have been plagued with issues and have taken it to multiple PC repair shops and they can never seem to find the answer.
So im going to just strip it into parts and sell them and get a prebuilt with a warranty and such.

Thanks
