I've got 2 rPis - a pi5 running Home Assistant and a pi4 with a USB drive caddy acting as little more than a NAS (it also does all the downloading through radarr etc.. )
I find them perfectly adequate.
My gaming rig acts as my emby server as it's basically on all the time and it has a beefy gfx card that can handle transcoding.
Judo is more focussed on throwing and grappling than it is on joint locks and holds, or "folding".
The more you know.
