Instead of buying an pre-assembled system, I would check out the Linux Hardware Comparability lists, go online and purchase the parts to build my own.
With UEFI possibly locking out many Linux Distros with OEM’s that kowtow to Mickey$oft, I am less likely to purchase any pre-built computer I intend to install and run Linux.
Some Distros have their own lists, such as Debian, the only Distro I install and use.
A Google search will reveal others. Good Luck!
