fire7side unless you dont know what you want from a computer, then sure, you will pay a convenience tax on pre built ones.
But you better start learning how to build a computer yourself, and then you could make a better purchase.
As for linux issue, with an old components that you have, there should be no problems there, with newer components you might run into issues. (ddrivers for nvidia)
Im using win11 because linux is still not ready for me. If you doing strictly gaming then using AMD GPU on linux is far more less headaches than nvidia. I use my rig for gaming and some other compute work, some AI stuff, with that, nvidia is king. Also i have multi monitor multi resolution multi refreshrate setup, here is where linux failed me.. Turns out you cant do theese things without headaches.. it wasnt convenient enough for me.
But my next pc, whereever i get a chance to upgrade, is gon be linux, atleas i will try, again.. 🙂
If you have single monitor setup, then there shoiuld be no problems with using any modern linux distro.
The only few problems i ever had (PopOS) with bluetooth speaker, it worked for 3 months then one day it just could not connect/pair with my speaker, took me hour to reboot, update, reboot, try try try.. untill it finally did it.. idk what happened, linux does not do automatic updates unless you set it up to do it.. i didnt, nothing was installed, it just broke one day.. But since that day, that PC is working... It has AMD 7xxx CPU and intel arc GPU..
packrat With arch, and blender, i had problem on my laptop, when im on wayland the touch controls (touchscreen) is not recognized by blender (for sculpting with pen), and it only works on x11.. still usable.
