In this context, "generic mini-PC" doesn't need to even be "non-gaming-PC", just not a platform for buying Valve's games; a razor-and-blades model requires that you be the one selling the blades. If someone just goes and runs games purchased from GOG, that's already an issue for them.

It's why inkjet printer manufacturers, who do use this model, try to make it so stupendously difficult to use ink from competitors (outside of the bottled-ink printers, which don't use that model, where the manufacturers are fine with you doing that).

If it's priced well and idle power usage good, it can be a great home lab. Run all sorts of services on it. Host your own Google Drive/Docs/Photos alternatives with all the automated categorization like face detection sorting. Should be strong enough to run a lot of unrelated services off one machine. If I ever had gigabit internet, I'd probably try stuff like hosting a Matrix server. Self hosted RSS feed.

Would be great for videos. RDNA3.5 has good AV1 and HEVC encoder and decode I believe. I think h.264 got solid with RDNA3.5. Good for video usually means good for photos too. Probably audio. Blender support for AMD graphics cards continue to improve and game engines have generally always been good. Great for a computer lab to teach something like Godot

The compact media creation thing would be the big thing for me if I needed a computer and this was substantially cheaper than a Strix Halo minipc. Darktable, Kdenlive, Krita, Ardour, Godot, Blender. I'd have people in mind where a $500-600 just under an ~RX 7600 would be a huge upgrade for their personal art workstation and the compact form is a big plus

Could be good for some home automation workflows- plex server, transcribing security cam video, doing object detection on said video.
