I really think that most people who think that they want ARM machines are wrong, at least given the state of things in 2024. Like, maybe you use Linux…but do you want to run x86 Windows binary-only games? Even if you can get 'em running, you’ve lost the power efficiency. What’s hardware support like? Do you want to be able to buy other components? If you like stuff like that Framework laptop, which seems popular on here, an SoC is heading in the opposite direction of that – an all-in-one, non-expandable manufacturer-specified system.
But yours is a legit application. A non-CPU-constrained datacenter application running open-source software compiled against ARM, where someone else has validated that the hardware is all good for the OS.
I would not go ARM for a desktop or laptop as things stand, though.
