I mean… back in the days I would never have bought a uATX board. You need expansion slots, after all, video, sound, TV, network, at least.

Nowadays? Exactly one PCIe slot occupied by the graphics card. Soundcards are pointless nowadays if your onboard doesn’t suffice for what you want to do you’d get an external audio interface, have it away from all that EM interference in the case, TV we’ve got the internet, NIC is onboard and as I won’t downgrade my network to wifi that’s not needed, either.

As far as I’m concerned pretty much all of my boards were an upgrade while also simultaneously becoming more and more budget.
