Will a PC built for Linux really make a difference?

Hello folks, I need to buy a new computer and I would like to use Linux. I'm not tech-savvy, but I've been using Lubuntu for the past 8 years (just basic use).

My new computer will be used for music production. Should I go for a made-for-Linux PC? I've been looking at 3 models in particular:

• The Kubuntu Focus NX ( https://kfocus.org/order/order-nx.html )

• The Tuxedo Nano Pro ( https://www.tuxedocomputers.com/en/Linux-Hardware/Linux-Computers-/-PCs/AMD-Systems/TUXEDO-Nano-Pro-Gen11.tuxedo )

• The Manjaro Mini PC ( https://manjarocomputer.eu/index.php/manjaro-mini-pc-amd-ryzen-7.html )

Since music production in Linux is (according to general consensus) not as easy or smooth as on other OS, I thought a made-for-Linux PC could make things a bit easier (no personal experience, just hearsay)

I don't like buying new (always second-hand), but if these PCs are reliable, well-built and optimised for Linux... I'm ready to buy new. I need a PC that will serve me for at least 5-6 years, if not more.

What's you opinion? Which model would you suggest, if any? Any suggestion is welcome!

Best
