You're demand is really weird let me explain you a bit :
Proxmox and CasaOS are mainly use for servers
MX Linux and Windows are the opposite
So my first question is what will be this machine?
The second important question is why using Proxmox and CasaOS?
Proxmox is a hypervisor (a type 1 hypervisor) basically it's like VMware or virtualbox (that you run as app in your OS), but has the place here as the main OS.
CasaOS on the other side is a bit different, it's more an user friendly self hosting service.
So you cannot really use the both if the machine is meant to be a server.
And lastly sure you can dual boot windows and MX Linux (even if windows will surely eat your MX Linux partition, and wouldn't recommended it).
But again you cannot really use your PC as a server and as a home at the same time ;-)
Humans are not 100% reliable too.
Don't make me wrong, I not promoting the use of AI (on the contrary I'm more against it)
But you must admit that I'm totally false in my says.
You don't think that at the time of the first computers people were saying the same thing as today about AI?
I my opinion you're partially right.
Yeah AI doesn't solve any problems by itself, humans can already do it.
AI is just humans but faster and more efficient (surely this create other serious problems like employment and more...)
But in this direction is the computer too, resolving no problems, before computers, humans were called computers, and they were doing the job of today iron computers.
They didn't resolve problems too, just faster while creating others important social issues
I agree with that point of view but at the same time, it's mostly false.
AI resolve problems that cannot be resolved by a dummy calculator.
Surely AI are not the best in pure calculations but it's not there main goal (unless it is explicitly designed for it)
I dont want that of a beast but only a cheap and decent smartphone that will supported by most of the Mobile Linux Distros to use a phone completely privately instead of using android
But you shouldn't use any apple product, they are as bad for privacy as using Google's one. Do not use an iPhone (lineageos is pretty good to use), do not use Apple's services... And keep going
