Used Dell Precision 5530 laptop. it has a 512 gigabyte NVME and 16 gigabytes of lpddr4 memory. The bios doesn't show it for some reason but it does have the Nvidia Quadro P1000 workstation GPU (equivalent to a mobile gtx 1050 more or less). Drive is cleared and new thermal paste has been applied, all you have to do is put an operating system on it
