I'm considering switching to an ARM-based desktop for my next computer, but I'm not familiar with the current options. How do ARM desktops compare with x86 systems in price, performance, power consumption, upgradeability, and ECC memory support? Are there any good ARM machines or components available for someone who wants a practical desktop rather than a laptop-style all-in-one or a small hobbyist board?

Software availability is probably the biggest issue. Many desktop applications are still primarily distributed for x86-64, while ARM software is often aimed at phones, tablets, or small development boards. Some programs do have ARM64 Linux builds or can be compiled from source, but that may require extra work and won’t always provide the same support as an official x86 release.
ARM can be efficient, and Linux generally runs well on it. Windows on ARM is usable too, but compatibility and performance can vary when software has to run through x86 emulation. Check the applications you depend on before buying, especially professional tools, games, drivers, and hardware utilities.
If you want a conventional desktop that you can upgrade over time, x86 is still the safer choice. ARM may become more competitive as hardware and software support improve, but today its advantages are mostly found in efficiency and tightly integrated systems rather than lower-cost, user-built desktops.
There are a few higher-end ARM workstation and server systems, including machines using Ampere processors, but they’re niche and usually Linux-focused. Apple’s desktop systems are another polished ARM option, though they use a closed ecosystem and offer limited upgradeability. ECC support, expansion slots, and memory choices depend heavily on the specific platform rather than ARM itself.
For a self-built, upgradeable desktop, ARM still doesn’t have anything close to the mature motherboard, CPU, and expansion-card ecosystem that x86 has. Most ARM choices today are laptops, mini PCs, single-board computers, or specialized systems. Standard desktop cases and interchangeable components are still uncommon, so you’d usually be buying a complete system rather than assembling one.

That makes sense. I’ll check whether the programs I use have native ARM64 versions before looking at hardware.
