I posted elsewhere about my setup. I have a rig in one room and a mini PC set up as a “console” using HoloISO connected to a TV. I stream games to it.
If it’s your only rig I recommend what the other person said. Get a full PC or catch a gaming laptop on sale unless you have a very specific use case. You can play modern games on higher end ones but you’ll get more bang for your buck out of a PC. You can make your own Ship of Theseus and upgrade parts one at a time.
