Maybe you can get a rip-roaring machine, but how so if that post 2005 computer can't boot of NVMe? What do you do, take the UEFI info and the /boot off another drive, and use the NVMe for / ? Or do you boot off another drive, and then carve up the (assumedly small) NVMe into /usr, /lib, /run ? Life gets a lot more complicated if the machine can't boot the NVMe.
