I would suggest to find out more about Clevo laptops, for example here:
https://www.clevo.com.tw/index.html
About prices you could find out here:

I am using Oryx Pro 4 which means CLEVO P955ER but with higher price https://www.xoticpc.com/sager-np8955-clevo-p955er.html
So I would recommend to buy Clevo directly without System76 or any other company who sell this Brand with overprice.
