I've built multiple living room, consoles PCs.

The experience is nowhere near the same.

- OSs do not compare fairly to how easily and care free is the UX on consoles: press one button, press another and you're in game

- Most PC games have issues with local coop, especially when it comes to bluetooth controllers, some games don't even release with local coop on PC, but they do on consoles

- Many games still expect a keyboard and mouse and won't popup the virtual keyboard when playing with a controller.

- The OS itself will not work with just a mouse and keyboard

- Dimensions are much bulkier, there's virtually no low profile well performing GPUs anymore since a decade

Honestly comparing a PC to a console is nonsense. It's a very different experience. Unless you're playing at your desk, then they are equivalent.
