Need Buyer Guide for Qubes OS System / Advice for Hardware

[PCUserGuy]

Hey guys,

i want to build an own system for Qubes OS. But i dont know which parts work quite well and i think the hardware compatibility list is not offering powerful hardware. 

I want to work with Qubes OS really smooth and i dont really have a price limit for this system. So all functions should work.

I am using a 4K Curved Monitor, so there should be enough power to let it look awesome on this screen. Furthermore i am fully new to qubes in general.

So, if someone in here got a good running system, please be exposed telling me right here.

Would be awesome! Qubes Version will be 4.0.3.
