Only use jellyfin. Have a list of things want to update… but it works for now.
Yes that is a laptop usb cooler used as supplemental placebo cooling. Also a pc fan I have propped up against the hard drive feeding into the pi.
Can’t recall last time used the ps4 or switch. But they’re there
Each Pi 4 has 8GB of RAM. With six devices, that’s 48GB to play with. More than enough for my needs.
