This is the thing I'm replying to, emphasis on the prebuilt.

Buying the same build as a prebuilt brings a premium and costs around 1000

For 1k you can get a 9600 9060XT 16gb system, which is waaaaaay more powerful, so this is quite an exaggeration.

But yeah, I don't think the machine will cost the same as a prebuilt, but that's the high end of the price range.
