I definitely can’t tell the difference for anything above 120hz or so, but I recall reading an article about counter strike several years ago, which showed that pro players can see an increase in performance with higher refresh rates up to about 300 or 350 hz (as long as you have the fps to match it, lol).
I have a ton of home automation dashboards around my house, and they’re awesome. Friends that stop by love them, although they have no technical skills to build these themselves (basically a raspberry pi with an lcd panel showing some specific home assistant dashboard, or monitoring webpage, etc).
I think there’s a decent market here for a company like Apple that can make it more accessible.
I do the same but with 2.5 inch sata ssd’s, and a hot swap bay in the front of my case. Swapping the OS is like using an old cassette player, now with 2TB of storage haha.
I kind of wish u.2 drives could take off in the same way, so I could do the same thing but with direct nvme storage.
