They are all in effect laptop-grade systems built in to monitors.

None are suitable for gaming etc., just basic desktop type stuff.

I would _never_ advise getting an all-in-one machine for general use, they are not upgradable and if anything goes wrong you have to replace the whole machine.

If you want a minimal-power machine with a bigger screen, get a mini PC or a secondhand Mac Mini and a standard monitor, whatever size suits you.
