I’m not suggesting it can do those things. You said no known system or console can wake on a Bluetooth connection, I said PS4 can. I don’t have a PS5, but it probably does too.

My PS4 wakes up when the bluetooth controller connects to it.

I already built my own loungeroom PC 18 months ago with a used rx580, amd 5600X, and 32gb RAM. This was just before the RAM crisis, so 32gb DDR4 was relatively cheap. I run Bazzite on it, and get a very SteamOS-like experience. Whole thing cost me less than half what they are asking for a Steam Machine.

This one is more like a very advanced raspberry pi. It is a powerful computer in your pocket with network jacks, wifi, Bluetooth and HDMI. It can be used for network analysis, penetration testing, software development. What it will actually be used for: plugging into your TV to stream movies.
