You can have a TV without a keyboard. Keyboard and mouse sets are cheap. You can buy it for less than 100 yuan. In addition, you need to have access to the Internet.

It is enough to be used as a machine for learning Linux. I often use it to debug my linux programs and services. Of course practicing is enough.

If you buy a domestically produced Raspberry Pi, it may be as cheap as 230. But I have never bought one so cheap. There should be more than 300 including keyboards. If you buy a second-hand TV or something like that, it might cost more than 400. A second-hand car monitor will do, it’s very compact.

Maybe it will cost more than 600 yuan. It is indeed a fully functional computer.
