Personally I'd love to have a smaller PC for gaming, but I've been scared off by Mini-ITX supposedly being harder to work with and tending to have worse cooling and therefore worse noise. I wish PCs were less fiddly to put together.
replyMini-ITX is harder to work with and usually does have worse cooling.
replyThere's just less space, so it's harder to get things in and out. And you have a smaller cooler because there's less space, at least for air cooling.
I haven't used itx with video cards, but that's hugely constrained...
But then how will you fit your action figures and extra displays that go in your case?
replyThey were obsolete a decade ago, but priced out by artificially expensive "SFF PC" cases, fans, and power supplies. PC building completely transitioned to fashionable cargo cult in the late 2010's, with the rise of twitch.
